WebApr 12, 2024 · 1 - IIR versur FIR. An IIR filter will have less phase shift than a FIR filter for the same cut-off frequency. 2 - Cut-off frequency. For an IIR low-pass filter, a filter with 0.1 Fs cut-off frequency will have a higher phase-shift than a with a 0.2 Fs cut-off frequency. An all-pass filter i.e. a gain of 1 has no phase shift. 3 - IIR filter order Webfollowing: Filter the signal with low-pass filter.
