On time delay estimation using an fir filter

Web4 Answers. To 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 asymmetric). A linear phase means that all frequency ... WebWindow, specified as a column vector. The window vector must have n + 1 elements. If you do not specify window, then fir2 uses a Hamming window. For a list of available windows, see Windows.. fir2 does not automatically increase the length of window if you attempt to design a filter of odd order with a passband at the Nyquist frequency..
