WebThe Butterworth filter is a type of signal processing filter designed to have as flat frequency response as possible (no ripples) in the pass-band and zero roll off response in the stop-band. Butterworth filters are one of the most commonly used digital filters in motion analysis and in audio circuits. They are fast and simple to use. WebThe notch filters are generally used to reject a particular frequency from a system. For example, the noise of 50 Hz or 60 Hz due to power-line interference can be easily removed from different systems using notch filters. ...

WebMay 23, 2016 · 2 Answers. Sorted by: 2. The main idea behind the notch filter is to zero out a small amount of frequencies in the FFT image, which causes noises. In order to find them, you can look at the FFT magnitude: F = abs (ft2); F = log (F+1); imshow (F, []) It is possible to see that the peaks in the frequency image, are located at the following points: The frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a logarithmic Bode plot, the response slopes off linearly towards negative infinity. A first-order filter's response rolls off at −6 dB per octave (−20 dB per decade) (all first-order lowpass filters have the same normalized frequency response). A second-order filter decreases at −12 dB per octave, a third-order at −1…
