Chapter 4

Frequency Response

Abstract

A discussion has been made on a frequency response where digital signal processing is performed. The goal to modify the frequency representation of a signal through filtering is the most elemental signal processing functions. Gradually, the discussion moves toward the responses and the complex exponential factors affecting it. It also touches on how to use a filter to normalize the response, when an input frequency is put through. The chapter also uses digital filter as a linear device to change the amplitude and phase of the input signal.
