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 ... WebCompared to IIR filters, FIR filters offer the following advantages: They can easily be designed to be “linear phase” (and usually are). Put simply, linear-phase filters delay the input signal but don’t distort its phase. They are simple to implement. On most DSP microprocessors, the FIR calculation can be done by looping a single ...
