During the course of the semester, several homework sets will be assigned. A subset of the answers for each homework set will be graded for credit. Solutions will be provided subsequently.

- Pulse modulation: Sampling, pulse-amplitude modulation, quantization, pulse code modulation.
- Data compression.
- Amplitude modulation: Conventional AM, suppressed carrier AM, single side- band AM; time and frequency representation, bandwidth requirements, power efficiency, coherent and envelope detection.
- Frequency modulation: Time and frequency representation, bandwidth require- ments, demodulation techniques.
- Digital modulation . phase shift keying, frequency shift keying, amplitude shift keying.
- Performance of modulation systems in the presence of noise.
