Continuous-Time Butterworth Filters

August 10, 2019 by

In this lesson you will learn the characteristics of continuous-time or analog Butterworth filters and how to design a Butterworth low-pass filter to satisfy passband and stopband constraints. The design procedure shows you how MATLAB chooses the filter order and cut-off frequency. Understanding the characteristics of the Butterworth filter is critical to deciding when to use Butterworth filters in practice.
