Butterworth Filter Design/Evidence
Method evidence record

Butterworth Filter Design

The Butterworth filter is a type of signal processing filter designed to have the flattest possible frequency response in the passband while rolling off toward the stopband with a gentle slope. Introduced by Stephen Butterworth in 1930, it has become one of the most widely used filter designs in electrical engineering and digital signal processing due to its predictable and smooth frequency characteristics.
