Signals and systems II-Part III: Analytic signals and QAM data transmission

This six-part series is a mini-course, focused on system concepts, that is aimed at the gap between Signals and Systems and the usual first DSP course. Part II discussed oversampling in D/A conversion and the basics of decimation, complex signals, and Nyquist signaling. This third article in the series is about analytic signals and linear data modulation. Figures are numbered in one sequence across the entire series, and gaps appear in their numbering in some individual articles.
