Chapter 5

Fourier Analysis for Discrete-Time Signals and Systems

Chapter Objectives

  • Learn the use of discrete-time Fourier series for representing periodic signals using orthogonal basis functions.
  • Learn the discrete-time Fourier transform (DTFT) for non-periodic signals as an extension of discrete-time Fourier series for periodic signals.
  • Study properties of the DTFT. Understand energy and power spectral density concepts.
  • Explore frequency-domain characteristics of DTLTI systems. Understand the system function concept.
  • Learn the use of frequency-domain analysis methods for solving signal-system interaction problems with periodic and non-periodic input signals.
  • Understand the fundamentals of the discrete Fourier transform (DFT) and fast Fourier ...
