前言

  Continuing the tradition of the first through the sixth editions of Digital and Analog Communication Systems, this new edition provides the latest up-to-date treatment of digital communication systems. It includes numerous updates and new sections on satellite radio broad-casting systems, cable data modems, and wireless data networks, such as Wi-Fi (IEEE 802.11) and Wi-Max (IEEE 802.16) systems. It is written as a textbook for junior or senior engineering students and is also appropriate for an introductory graduate course or as a modem technical reference for practicing electrical engineers. For the first time a Student Solutions Manual is available for download on the web. Go to http://lcouch.us or http://couch.ece.ul.edu.

章节摘录

  A digital communication system transfers information from a digital source to the intended receiver (also called the sink).DEFINITION.An analog communication system transfers information from an analogsource to the sink.Strictly speaking, a digital waveform is defined as a function of time that can haveonly a discrete set of amplitude values. If the digital waveform is a binary waveform, onlytwo values are allowed. An analog waveform is a function of time that has a continuousrange of values.An electronic digital communication system usually has voltage and current waveformsthat have digital values; however, it may have analog waveforms. For example, the informa-tion from a binary source may be transmitted to the receiver by using a sine wave of 1,000 Hzto represent a binary 1 and a sine wave of 500 Hz to represent a binary 0. Here the digital sourceinformation is transmitted to the receiver by the use of analog waveforms, but the system is stillcalled a digital communication system. From this viewpoint, we see that a digital communica-tion engineer needs to know how to analyze analog circuits as well as digital circuits.
