www.analog.cominfinite impulse response (IIR). As the terminology suggests, these classifications refer to the filter’s impulse response. By varying the weight of the coefficients and the number of filter taps, virtually any frequency response characteristic can be realized with an FIR filter. As has been shown, FIR filters can achieve performance
