(3 units). Review of linear systems, the sampling theorem, and Fourier analysis. Noiseless analysis of the linear modulation schemes: double sideband, inphase-quadrature, single sideband, vestigial sideband and conventional AM. Superheterodyne receivers. Angle modulation: phase modulation, and frequency modulation. Carson's rule. Discriminator and phase-locked loop detection of FM. Basic digital modulation techniques: ASK, PSK, FSK. Bandwidth requirements of PAM (Nyquist's criterion). Pulse code modulation and companding. Introduction to error control coding and to information theory. Course Component: Laboratory, Lecture, Tutorial Prerequisite: ELG 3125. ELG 3126 is corequisite to ELG 3175.
