WebTo be precise the group delay of a linear phase FIR filter is ( N − 1) / 2 samples, where N is the filter length (i.e. the number of taps). The group delay is constant for all frequencies, because the filter has a linear phase, i.e. its impulse response is symmetrical (or … WebJan 25, 2024 · There are 4 types of linear phase FIR filters. You can also have an anti-symmetric impulse response (giving you an additional phase shift of $\pi/2$), and you have even length linear phase filters, where the symmetry is not about an integer sample number, but about a point in between two sample points. – Matt L.
