Web5) FIR filter consume low power and IIR filter need more power due to more coefficients in the design. disadvantage of FIR over IIR: 1) IIR filters are having fast computation speed as compare to FIR. 2) FIR filter require more memory as compare to IIR 3) Delay is more in FIR than IIR filter. Is FIR filter recursive or non recursive? WebInfinite Impulse Response (IIR) filtering is performed using a two-pass (once forwards, once reversed) method to correct for phase alignment. Note that the Butterworth filter designs used here can become numerically unstable with only a small increase in filter order. For most purposes, use FIR filters. Examples
