Abstract: This chapter concentrates on the frequency domain analysis of discrete time systems. Derivation and importance of sampling theorem, discrete time Fourier transform (DTFT), its properties and applications in digital signal processing and filter design are discussed in detail, along with many problems worked out numerically and by MATLAB functions. Derivation of discrete time Fourier Series (DTFS), discrete time Fourier Transform (DFT) and their properties is shown. Difference between their properties and the difference between circular convolution and linear convolution is explained. Application of Fast Fourier Transform (FFT) is included in this chapter
