Chapter 6The Fourier Transform
In this chapter, other orthogonal sets of signals are set aside to concentrate on the complex exponential 
. The complex Fourier series for periodic signals is logically extended into a continuous function of frequency suitable for both periodic and non-periodic signals. A thorough study of the continuous Fourier transform reveals the properties that make this transform technique a classic tool in signals analysis. By relating the time domain and frequency domain behavior of signals, the Fourier transform provides a unique perspective on the behavior of signals and systems. The Fourier transform also forms the basis for the Laplace transform in Chapter 8 and the 
-transform of Chapter 10.
