History: In Zhou Dynasty, there were some people named “染人”, “醯人” in charge of staining, making wine and making vinegar. But the foundations of organic chemistry date from the mid-eighteenth century, when chemistry was evolving from an alchemist’s art into modern science. At that time, unexplainable differences were noted between substances obtained from living sources and those obtained from minerals.

Taboo禁忌语PPT
Chinese and Western Taboos on Disease and Death
The word "death" means to say goodbye to life and to cause great grief to such people, so it is taboo to say this word in both Chinese and English.
e.g. In Western languages, people use C.C or Big C or long disease instead of cancer, and AIDS as communicable social disease. In Chinese, there are similar expressions, for example, "sick" is called "not feeling well".
Development stages
The primitive superstitious stage
The feudal patriarchal stage
The modern democratic stage
➢ Primitive stage: The funeral and the ancestor worship taboo are most directly related to ghost beliefs.
e.g. Such words are often expressed by the names of animals, such as “pig, swine, cow”, etc. The Chinese words “fuck” and “damn” are also forbidden. In English, for the “toilet” there are “washroom, bathroom”, for the “clothes and body parts” there come “corset, belly, cunt, buttock, women‘s shirt, and so on.

Thus, telecommunication means the process of exchanging information over a distance. Information is an intelligence signal which changes unpredictably with time.During communication, the message is transmitted from its source to a destination. This transmission is achieved by the use of a communication system.(Lathi) What are the components of a telephone system?Person who talks on a phone (message source)↓Telephone (transducer in which speech message is converted into electrical signal)↓Wire (transmission channel)↓Telephone (transducer in which electrical signal is converted back into speech message)↓Person who talks on a phone (message destination)What are the components of a television system?Person who dances (message source)↓Video camera (transducer in which image message is converted into electrical signal)↓Antenna (transmitter in which signal is modified for efficient transmission)↓Free space (transmission channel)↓Television (transducer in which electrical signal is received and converted back into image message)↓Person who watches television (message destination)In communication, the physical message, such as sound, word, picture, etc., is converted into an electrical message called signal and this electrical signal is conveyed at the distant place, where it is reconverted into the physical message through some media. Thus, a communication system has following components:The function of communication system componentsSource originates a message, such as a human voice, a television picture, or data.If the message is not electrical, it should be converted by an input transducer into an electrical waveform referred to as the baseband signal or message signal.e.g. in a telephone system, human voice is converted into an electric current variation.The transmitter modifies the message signal for efficient transmission.The channel is a medium such as wire, coaxial cable, an optical fiber, or free space – for signal transmission.The receiver reprocesses (demodulate) the output signal from the channel. The receiver output is fed to the output transducer, which converts the electrical signal into its original form, the message.The destination is the unit to which the message is communicated.In a communication system, a message must be converted into a signal before it can be transmitted in the transmission channel.What is a signal?A Signal is a set of information or data and is usually a function of time.A typical example of signal is the variation of electric current that contains message.During the signal transmission, noise will be added and it will affect the signal.Noise refers to undesired signal which carries no information. It is random and unpredictable signal produced by the natural processes both internal and external to the system. When such random variations are superimposed on an information-bearing signal and if the noise amplitude is larger than that of the signal, the message may cause signal distortion, which leads that the information cannot be correctly received.Distortion is waveform perturbation caused by imperfect response of the system to the desired signal itself. Unlike noise, distortion disappears when the signal is turned off.There are two types of noises, external noise and internal noise.The electrical noise that is introduced in the transmitting medium is termed external noise.The noise introduced by the components in the transmitter and receiver is known as internal noise. External NoiseMan-made noise: produced by electromagnetic waves generated by things like electric motors, power lines, etc. These waves will be converted by receiving antenna into electrical signals.Atmospheric noise: caused by naturally occurring disturbances in the earth’s atmosphere due to, e.g. lightning, etc.Internal NoiseInternal noise is produced by electronic circuits.There are two types of internal noise: thermal noise and shot noise.Thermal NoiseThermal noise is generated in a resistive component due to the rapid and random motion of electrons and atoms inside the component. This motion increases with increasing temperature (hence, “thermal”).This random motion of electrons produces an unpredictable component in a current passing through a resistor (hence, “noise”). Its frequency content is spread uniformly throughout the usable spectrum, hence it is also known as white noise. It is sometimes referred to as Johnson noise, after its discoverer.Thermal noise generationAt any temperature above absolute zero, thermal energy causes charged particles to exhibit random motion. The random motion of charged particles such as electrons generates random currents or voltages called thermal noise. Thermal noise exists in every communication system.Shot NoiseShot noise exists in all active devices, especially in transistors . It is caused by random variations in the arrival rate of electrons or holes (due to spontaneous recombination and generation) at the output of the device.There are other types of internal noise but they are relatively unimportant and hence will not be considered here.Shot noise and thermal noise are additive .Noise is one of the basic factors that set the limit of communication system performance.Signal-to-Noise Ratio (SNR or S/N) provides a comparison of noise and signal powers at the same point. It is defined asand in decibel form asQuestions1.Can you increase the SNR by amplifying the signal before the receiver? Why or why not?2. What type of noise does a transistor has?3. Find the SNR in dB if the ratio of signal power to noise power is:(a) 10 ?(b) 100 ?ModulationModulation is defined as the process by which some parameter of the high frequency carrier is varied in accordance with the message signal. This parameter may be the amplitude, the frequency or the phase ofthe carrier wave.S N P Signal Power SNR Noise Power P ==10()10log S N P SNR dB P =Notice that after modulation the signal transmission takes place at the high frequency carrier which has been modified to carry the lower-frequency message signal.What is the carrier wave?A sinusoidal wave of high frequency and one of its parameters is varied in proportion to the message signal In a communication system, the transmitter modifies the message signal for efficient transmission.How to perform modulation?In modulation, the information is carried on a high frequency “carrier” and the transmission takes place at the carrier frequency. Thus, the modulation can be performed by multiplying the message signal by a carrier wave (sinusoidal signal).e.g. g(t) = m(t) cos(ωc t)where m(t) is the message signal, or baseband signal, or modulating signal (signal before modulation), cos(ωc t) is the carrier wave, and g(t) is the modulated signal (signal after modulation).A modulator is a product device, it systematically alters the carrier wave in correspondence with the variations of the modulation signal and the resulting modulated signal “carries” the message information. Why modulation is needed? Why not just transmit the signal directly?The primary purpose of modulation in a communication system is to generate a modulated signal suited to the characteristics of the transmission channel. Actually, there are several practical benefits and applications of modulation briefly discussed below.Efficient transmission:Signal transmission over long distance always involves a traveling electromagnetic wave, with or without a guiding medium. The efficiency of any particular transmission method depends upon the frequency of the signal being transmitted. By the use of modulation, message information can be impressed on a carrier whose frequency has been selected for the desired transmission method.For efficient radiation of electromagnetic energy, the radiating antenna should have the physical dimension of at least 1/10 of the signal’s wavelength. For many baseband signals, the wavelengths are too large for reasonable antenna dimensions. For example, the frequency of a speech signal is in the range of 100 to 3000 Hz (in open space, fλ = c, where c is the light propagation velocity) and the corresponding wavelength is 100 to 3000 km. This long wavelength indicates an impracticably large antenna. By use of modulation, the low frequency speech signals can be used to modulate a high frequency carrier wave, thus translating the signal spectrum to the range of carrier frequencies that corresponds to a much higher frequency or in other words, much smaller wavelength.Frequency allocation:Modulation can effectively shift the frequency spectrum of the signal to the location centered on the carrier frequency.When you tune a radio or television set to a particular station, you are selecting one of the many signals being propagated at that time. Since each station has a different assigned carrier frequency, the desired signal can be separated from the others by filtering. Were it not for modulation, only one station could broadcast in a given area; otherwise, two or more broadcast stations would create a hopeless interference.Efficient spectrum utilization:The channel bandwidth may be much larger than the signal bandwidth. It would be wasteful if only one signal is transmitted over the channel. One way to solve this problem is to use modulation, which allows each signal spectrum be moved to its assigned frequency range without overlapping and thus will not interfere with each other. Thus several signals can be transmitted simultaneously in the same channel. This is known as Frequency Domain Multiplexing (FDM).MultiplexingBandwidth:Bandwidth (BW) is the portion of electromagnetic spectrum occupied by a signal.e.g. A signal frequency range is 902 to 928 MHz. What is the signal bandwidth?f1 = 902 MHz, f2 = 928 MHz, thenBW = f2 – f1 = 26 MHzWhat is the relation ship between the signal bandwidth and channel bandwidth (transmission bandwidth)? When a signal changes rapidly with time, its frequency is high or its spectrum extends over a wide range and hence the signal has a large bandwidth.Similarly, the ability of a system to follow signal variation is reflected in its frequency response or transmission (channel) bandwidth.A rapid signal variation ⇒ a large signal bandwidth ⇒ a large channel bandwidth requiredThe two fundamental limitations of information transmission are bandwidth and noise.The concept of bandwidth applies to both signals and systems. When a signal changes rapidly with time, its frequency content or spectrum extends over a wide range and we say that the signal has a large bandwidth. Similarly, the ability of a system to follow signal variation is reflected in its frequency response or transmission bandwidth.What is the consequence of insufficient transmission bandwidth?Communication under real-time conditions requires sufficient transmission bandwidth to accommodate the signal spectrum; otherwise, severe distortion will result.Every communication system has limited bandwidth that limits the signal speed.Noise imposes a second limitation on information transmission.Both the bandwidth and the noise limit the communication system performance.Classification of communication systems:A communication system is divided into two categories depending on the transmission media (channel) used: line communication system, and wireless communication system.In line communication, transmission is carried out on the transmission line.Examples of transmission line: wire, coaxial cable, optical fiber, etc.In wireless communication, signals from various sources are transmitted through a common media – open space.Examples of wireless communication: radio, microwave, etc.A communication system can be divided into analog communication system and digital communication system, according to the characteristics of transmitted signals.How to evaluate the performance of a communication system?The performance of a communication system is usually evaluated by two key factors:1.Efficiency determines the capacity of transmission channel;2.Reliability determines the signal quality.In an analog communication system, efficiency is measured by transmission channel bandwidth, B, and reliability is measured by system output signal-to-noise ratio (S/N).e.g. a single sideband telephone system requires 4 kHz bandwidth but a double sideband or a conventional amplitude modulation telephone system requires 8 kHz bandwidth, so that single sideband system has a higher efficiency than a double sideband or a conventional amplitude modulation system.e.g. a telephone system requires a S/N at least 20 dB and a TV picture needs its S/N above 40 dB.In a digital communication system, efficiency is measured by bit rate, R, and reliability is measured by bit error rate, P b.Bit rate: R = n/T (bits/sec) where n is the number of bits sent in T secondsBit error rate (BER): P b = number of error bits / total number of bitse.g. a digital telephone system requires P b < 10-3∼ 10-6 and data communication requires P b < 10-9.Review Questions1.What are the main components in a basic communication system?2.What is a transducer?

Seven-member South Korean boy band BTS also known as Bangtan boys has only debuted five years ago but they are rewriting K-pop history with every move. They are the first Korean musicians to enter the U.K. Albums Chart and break records with their released album "WINGS." They started out in small companies with no capital and heavy liabilities, and went to the world through their own efforts. Now the company has a market value of 1 trillion won, closely following the three major entertainment companies in Korea, which is the Korean idol industry myth.

The British Broadcasting Company (BBC) is formed in 1922 14 November – First BBC broadcasts from London (station 2LO). 15 November – First broadcasts from Birmingham (station 5IT) and Manchester (station 2ZY).
The BBC is established under a Royal Charter and operates under its Agreement with the Secretary of State for Culture, Media and Sport. Its work is funded principally by an annual television license fee which is charged to all British households, companies, and organizations using any type of equipment to receive or record live television broadcasts and iPlayer catch-up. The fee is set by the British Government, agreed by Parliament, and used to fund the BBC's radio, TV, and online services covering the nations and regions of the UK. Since 1 April 2014, it has also funded the BBC World Service(launched in 1932 as the BBC Empire Service), which broadcasts in 28 languages and provides comprehensive TV, radio, and online services in Arabic and Persian.
