2. FIR filter vs iir filter FIR filters have linear-phase characteristics, whereas IIR filters have non-linear phase characteristics. FIR filters are of non-recursive type,whereas IIR filters are of recursive type.Therefore FIR filters are always stable whereas IIR filters are unstable. FIR filters need more computation units compared to an IIR filter with similar response. FIR FILTERS ARE GENERALLY PREFERRED OVER IIR! FIR IIR 3.
