Abstract
In Chap. 4, the continuous time periodic signal x(t) was represented in Fourier series as a sum of sinusoids or exponentials. In this chapter, a similar development is made to represent the periodic discrete time signal x[n] by Fourier series. Even though the Fourier series can be expressed in trigonometric form, because of its compactness and ease of getting the solution, exponential form of Fourier series is preferred and is discussed in this chapter.
