Silicon microprocessors have been the heart of the computing world for more than 40 years. In that time,microprocessor manufacturers have crammed more and more electronic devices onto microprocessors. In accordance with Moore’s Law, the number of electronic devices put on a microprocessor has doubled every 18 months .Moore’s Law is named after Intel founder Gordon Moore ,who predicted in 1965 that microprocessors would double in complexity every two years. Many have predicted that Moore’s Law will soon reach its end because of the physical limitations of silicon microprocessors.The current process used to pack more and more transistors onto a chip is called deep-ultraviolet lithography ( DUVL), which is a photography-like technique that focuses light through lenses to carve circuit patterns on silicon wafers. DUVL will begin to reach its limit around 2005,At that time, chipmakers will have to look to other technologies to cram more transistors onto silicon to create more powerful chips.Many are already looking at extreme-ultraviolet lithography(EUVL) as a way to extend the life of silicon at least until the end of the decade. EUVL uses mirrors instead of lenses to focus the light, which allows light with shorter wavelengths to accurately focus on the silicon wafer.Beyond EUVL, researchers have been looking at alternatives to the traditional microprocessor design. Two of the more interesting emerging technologies are DNA computers and quantum computers.DNA computers have the potential to take computing to new levels, picking up where Moore’s Law leaves off. There are several advantages to using DNA instead of silicon:As long as there are cellular organisms, there will be a supply of DNA makes it a cheap resource.Unlike traditional microprocessors, which are made using toxic materials, DNA biochips can be made cleanly.DNA computers are many times smaller than today’s computers.DNA’s key advantage is that it will make computers smaller, while at the same time increasing storage capacity,than computer that has come before. One pound of DNA has the capacity to store more information than all the electronic computers ever built. The computing power if a teardrop-sized DNA computer, using the DNA logic gates, will be more powerful than the world’s most powerful supercomputer. More than 10-trillion DNA molecules can fit into an area no larger than 1 cubic centimeter (.06 inch3). With this small amount ofDNA ,a computer would be able to hold 10 terabytes(TB) of data and perform 10-trillion calculations at a time. By adding more DNA, more calculations could be performed .Unlike conventional computers could perform calculations simultaneously. Conventional computers operate linearly, taking on tasks one at a time. It is parallel computing that will allow DNA to solve complex mathematical problems in hours-problems that might take electrical computers hundreds of years to complete.Today’s computers work by manipulating bits that exist in one of two states: 0 or 1. Quantum computers aren’t limited to two states; they encode information as quantum bits, or qubits. A qubit can be a 1or a 0, or it can exist in a superposition that is simultaneously 1 and 0 or somewhere in between. Qubits represent atoms that are working together to serve as computer memory and a microprocessor. Because a quantum computer can contain these multiple states simultaneously, it has the potential to be millions of times more powerful than today’s most powerful supercomputers. A 30-qubit quantum computer would equal the processing power of a conventional computer capable of running at 10 teraops, or trillions of operations per second. Today’s fastest supercomputers have achieved speeds ofabout 2 teraops.Already we are seeing powerful computers in non-desktop roles. Laptop computers and personal digital assistants(PDAs) have taken computing out of the office. Wearable computers built into our clothing and jewelry will be with us everywhere we go. Out files will follow us while out computer provides constant feedback about our environment. V oice- and handwriting-recognition software will allow us to interface with out computers without using a mouse or keyboard . Magnetic RAM and other innovations will soon provide our PC with the same instant-on accessibility that our TV and radio have.One thing is an absolute certainty: The PC will evolve. Ti will get faster. It will have more capacity. And it will continue to be an integral part of our lives.硅微处理器成为计算世界的中心已经超过40年。

Mobile Wireless
To prevent interference between cells, the first type of mobile wireless communications system, which is referred to as the Analog Mobile Phone System (AMPS), employed a seven cell pattern, as illustrated in Fig.13 1. The cell pattern shown in Fig.13 1 ensures that no adjacent cells operate on the same frequency. In actuality, each cell consists of a base station and antenna that supports operations over a wide range of frequencies. However, only one call can occur at one of the frequencies supported in a cell at any given time; the cell pattern is used to ensure that two adjacent cells do not use the same frequency at the same time.

电子信息工程专业英语教程第三版译者:唐亦林p32In 1945 H. W. Bode presented a system for analyzing the stability of feedback systems by using graphical methods. Until this time, feedback analysis was done by multiplication and division, so calculation of transfer functions was a time consuming and laborious task. Remember, engineers did not have calculators or computers until the '70s. Bode presented a log technique that transformed the intensely mathematical process of calculating a feedback system's stability into graphical analysis that was simple and perceptive. Feedback system design was still complicated, but it no longer was an art dominated by a few electrical engineers kept in a small dark room. Any electrical engineer could use Bode's methods find the stability of a feedback circuit, so the application of feedback to machines began to grow. There really wasn't much call for electronic feedback design until computers and transducers become of age.1945年HW伯德提出了一套系统方法,用图形化方法来分析反馈系统的稳定性。
