http://www.dspguide.com/ch19.htm Web5 apr. 2024 · The IIR filter is recursive. The FIR filter is non-recursive in nature. IIR filters are less stable than that of FIR filters due to the presence of poles. FIR filters do not contain any poles. Hence the FIR filter is always stable and the stability is more than that of IIR filter. The transfer function of IIR filter contains both poles and zeros.
