High pass filter code in matlab
WebMay 11, 2012 · The code includes a butterworth high pass filter and the "cumtrapz" integration code. Applying the code to a square wave, the wave becomes distorted. Does it mean my code is not good enough or the square wave will always be distorted by the filter. WebJan 2, 2011 · H_hp (w) = 1 - H_lp (w) So if you want your high-pass filter to pass from K to pi, design a low-pass, which you already know how to do, that passes from 0 to K, then use the equation above to find the high-pass frequency response, and then take the IFFT of H_hp.
