chapter 2 Complex SignalsA number of signal processing applications make use of Complex Signals . Someexamples include the characterization of the Fourier transform, blood velocityestimations, and modulation of Signals in telecommunications. Furthermore,a number of signal -processing concepts are easier to derive, explain and un-derstand using Complex notation. It is much easier, for example to add thephases of two Complex exponentials such asx(t) =ej 1e 2, than to manipulatetrigonometric formula, such as cos( 1) cos( 2).We start by introducing Complex Signals in Section , and treating theFourier relations in Sec.
