With digital modulation, however, discrete changes in the light intensity are obtained (i.e. on-off pulses). Although often simpler to implement, analog modulation with an optical fiber communication system is less efficient, requiring a far higher signal to noise ratio at the receiver than digital modulation.

电子信息专业英语(第二版)课件：Telecommunications
The golden age of automatic telephony occurred after World WarⅡwhen the entire long-distance network was automated. The invention of the transistor spurred the application of electronics to switching systems and led to the deployment of the first electronic switching in the late 1950s. Electronic switching made it possible to design and build switches with greater capacity.
Satellite communication was first proposed in 1945 by the British science fiction writer, Arthur C. Clarke. Satellite communications became a reality with the launching of the Russian satellite Sputnik (in 1957) and the American satellite Explorer (in 1958). The AT&T Telstar was the first experimental satellite capable of relaying television (TV) programs across the Atlantic Ocean. It was launched from Cape Canaveral(now Cape Kennedy)on July 1962. The first global civil communications satellite, INTELSAT Ⅰ(Early Bird), was launched in April 1965.

Unit 24 Others
In contrast with the Echo series, the TelstarⅠactive communications satellite launched in 1962 carried receiving and transmitting equipment. It was an active participant in the reception-transmission process. As the satellite received a signal from a ground or earth station, a communications complex that transmitted and/or received satellite signals, it relayed its own signal to earth.［1］ Telstar also paved the way for today’s communications spacecraft since it created the world’s first international satellite television link.
Unit 24 Others
During the span of years that separates TelstarⅠfrom today’ satellites, there have been a number of improvements. For example, spacecraft such as Telstar and Echo were placed in low earth orbits. In this type of orbital position, a satellite traveled at such a great rate of speed that it was visible, and hence usable, to an individual ground station for only a limited period of time each day. The satellite appeared from below the horizon, raced across the sky, and then disappeared below the opposite horizon.

电子信息类专业英语Unit 14 Digital Signal Processing-PPT精品文档
Text
What is DSP? DSP, or Digital Signal Processing, as the term suggests, is the processing of signals by digital means. A signal in this context can mean a number of different things. Historically the origins of signal processing are in electrical engineering, and a signal here means an electrical signal carried by a wire or telephone line, or perhaps by a radio wave. More generally, however, a signal is a stream of information representing anything from stock prices to data from a remote-sensing satellite.
Unit 14 Digital Signal Processing
Signal Processing
Signals commonly need to be processed in a variety of ways. For example, the output signal from a transducer may well be contaminated with unwanted electrical“noise”. The electrodes attached to a patient’s chest when an ECG is taken measure tiny electrical voltage changes due to the activity of the heart and other muscles. The signal is often strongly affected by “mains pickup”due to electrical interference from the mains supply. Processing the signal using a filter circuit can remove or at least reduce the unwanted part of the signal. Increasingly nowadays, the filtering of signals to improve signal quality or to extract

ASP vs. DSP Today’s engineer faces a challenge in selecting the proper mix of analog and digital techniques to solve the signal processing task at hand. It is impossible to process real-world analog signals using purely digital techniques, since all sensors (microphones, thermocouples, strain gages, piezoelectric crystals, disk drive heads, etc.) are analog sensors. Therefore, some sort of signal conditioning circuitry is required in order to prepare the sensor output for further signal processing, whether it be analog or digital. Signal conditioning circuits are, in reality, analog signal processors, performing such functions as multiplication (gain), isolation (instrumentation amplifiers and isolation amplifiers),
With respect to DSP, the factor that distinguishes it from traditional computer analysis of data is its speed and efficiency in performing sophisticated digital processing functions such as filtering, FFT analysis, and data compression in real time.

The term mixed signal processing implies that both analog and digital processing is done as part of the system. The system may be implemented in the form of a printed circuit board or a single integrated circuit chip. In the context of this broad definition, ADCs and DACs are considered to be mixed signal processors, since both analog and digital functions are implemented in each. Recent advances in Very Large Scale Integration (VLSI) processing technology allow complex digital processing as well as analog processing to be performed on the same chip. The very nature of DSP itself implies that these functions can be performed in real-time.
