Engineering Design Statement:

The lectures will emphasize both the design and analysis of communication circuits. Topics will include: impedance matching networks, oscillators, mixers, modulators, demodulators, and phase-locked loops. Design trade-offs involving performance and cost will be considered.

The homeworks and examinations will contain both design and analysis problems.

The laboratory projects will consist of designing, analyzing, and building simple AM and FM transmitters and receivers.
