WebThe symmetrical highpass and lowpass filters have to be designed in such a way that they possess a roll- off which is as sharp possible. This however, generally implies high filter orders which is not aspired in a real solution involving video bandwidths. Moreover these filters have to be linear-phase FIR filters in order to WebMay 29, 2012 · To use the filter on your data, you can either do filter (b,a,data) or filter (Hd,data) depending on what filter you eventually use. If you want zero phase distortion, use filtfilt. However, this does not accept dfilt objects. So to zero-phase filter with Hd, use the filtfilthd file available on the Mathworks file exchange site EDIT

Solution: Since the cutoff frequency of 3800 Hz is much larger than fs /4 = 2000 Hz, we determine the pole as

WebIt is a full-rate, 7-tap Halfband FIR filter, which takes a 16-bit sample and outputs a decimated/half-rate 16-bit sample with 2 cycle delay. A 7-tap filter with 6% usable pass-band (90 dB rejection) doesn't seem useful but it is great when doing large decimations. Ex: 128M -> 4M (0.48M usable) can be achieved by cascading 5 such filters. ...
