Frequency Response Magnitude and Poles and Zeros

August 10, 2019 by

The magnitude of a system's frequency response is tightly coupled to the locations of the poles and zeros. In this lesson you will learn how to infer the nature of the frequency response magnitude from the poles and zeros. This skill is very useful when designing and evaluating filters. The insight linking frequency response magnitude and poles and zeros is another benefit of analyzing systems with the z-transform.
