Course Description: 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.

Assignments and quizzes
are done in class or tutorial periods.
Some are done in groups and some individually. In the event that a tutorial will be used
for other purposes (such as midterms or extensive problem solving session) then
the quiz may be held in class time. There
may be Matlab programming assignments as well. These are to be handed in. There will be two midterms. The closed book midterms will be done in the
tutorials in weeks 4 and 7. The better
of the two midterms is worth 12% and the other is worth 8% of the final
mark. The final exam is also closed
book.
