6.1      Introduction

The response of a system to an input can be characterized in a variety of formats. Most commonly, the response is given in either the time domain, by the impulse response, or in the frequency domain, by the frequency response. Of interest here is the frequency response, a measure of the relationship of a system’s output ...
