The present work stresses a mathematical systems approach to all aspects of analog and digital communications, encompassing signal analysis, linear systems, probability and random analysis, amplitude modulation, angle modulation, pulse modulation, and digital transmission and reception. Attention is given to...
This edition features a section which addresses consumer and commercial uses of spread spectrum systems. Comprehensively describes techniques so readers can readily apply them to actual situations.Robert C. DixonR. Carson, Radio Communications Concepts: Analog , 1994 :Wiley Interscience...
Based on either the nature of signals which are transmitted or by nature of the information the communication system may be digital. If even one of them is digital then we consider it as a digital communications system. Based on data and signal types there are a total of four possible combi...
Analog and Digital Control System Design : Transfer-Function, State-Space, and Algebraic Methods / C.T. Chen Publisher's description: This text's contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated...
The basic electron beam coder concepts are shown in Figure 2.6 for a 4-bit device. The early tubes operated in the serial mode (A). The analog signal is first passed through a sample-and-hold, and during the "hold" interval, the beam is swept horizontally across the tube. The Y-...

DACs used in audio and communications quite often do not even have traditional static specifications listed on the data sheet, and various noise and distortion specifications are of much more interest. However, the 5.1 ANALOG-DIGITAL CONVERSION traditional static specifications such as differential ...

Sampling and quantization are important concepts because they establish the performance limits of an ideal ADC. In an ideal ADC, the code transitions are exactly 1 least significant bit (LSB) apart. So, for an N-bit ADC, there are 2N codes and 1LSB= FS/2N, where FS is the full-scale...
They are all closely related, and sometimes this close relationship causes confusion. Once understood, however, the concepts are fairly simple. The Nyquist-Shannon sampling theorem states that for a true representation of waveform X, greater than 4 High-Speed, Analog-to-Digital Converter Basics ...
