Chapter 3 Fourier Series Representation of Period Signals

3.2 The Response of LTI Systems to Complex Exponentials It is advantageous in the study of LTI systems to represent signals as linear combinations of basic signals that possess the following two properties: • The set of basic signals can be used to construct a broad and useful class of signals.
