ECE 5520: Digital Communications Lecture Notes Fall 2009

A digital communication system conveys discrete-time, discrete-valued information across a physical channel. Information sources might include audio, video, text, or data. They might be continuous-time (analog) signals (audio, images) and even 1-D or 2-D. Or, they may already be digital (discrete-time, discrete-valued). Our

MatlabTutorial : Root Locus

2.0 Root Locus Design Consider all positive values of k. In the limit as k -> 0, the poles of the closed-loop system are a(s) = 0 or the poles of H(s). In the limit as k -> infinity, the poles of the closed-loop system are b(s) = 0 or the zeros of H(s). No matter what we pick k to be, the closed-loop system must always have n poles, where n is the

Control was manual, and the control channel was open for anyone to hear. In fact, users were required to be listening to the control channel. When the switching operator wanted to connect to any mobile user, they would announce the call on the control channel. If the user responded, they would tell the user which voice channel to turn to.

Discrete-time signals and systems

More precisely the support interval of a continuous-time signal xa(t)is the smallest time interval1 [t1;t2]such that the signal is zero outside this interval. For a discrete-time signal x[n], the support interval is a set of consecutive integers: fn 1 ;n 1 +1;n 1 +2;:::;n 2 g.
