Differences in transforming a sinc FIR filter from lowpass to …

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 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. ...
