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

3. The Finite-Difference Time- Domain Method (FDTD)
my.ece.utah.edu3. The Finite-Difference Time-Domain Method (FDTD) The Finite-Difference Time-Domain method (FDTD) is today’s one of the most popular technique for the solution of electromagnetic problems. It has been successfully applied to an extremely wide variety of problems, such as scattering from metal objects and
MatlabTutorial : Root Locus
my.ece.utah.edu2.0 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

my.ece.utah.eduControl 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.

Spatial Signal Processing (Beamforming)
www.personal.psu.edu• Beamforming is spatial filtering, a means of transmitting or receiving sound preferentially in some directions over others. • Beamforming is exactly analogous to frequency domain analysis of time signals. • In time/frequency filtering, the frequency content of a time signal is revealed by its Fourier transform.
