EECS20N: Signals and Systems

Instructor Guide for Week 9

In this week, we consider linear, time-invariant (LTI) systems, and introduce the notion of frequency response. We show that a complex exponential is an eigenfunction of an LTI system. The Fourier series is redone using complex exponentials, and frequency response is defined in terms of this Fourier series, for periodic inputs.
