WebNDERSTANDING finite word-length (FWL) effects, in- cluding roundoff noise (RON), coefficient quantization noise (CQN) and limit cycles (LC), is essential in designing IIR digital filters. IIR filters have often been avoided in real- time high throughput applications because of the problematic recursive updates of IIR algorithms. WebThe purpose of this paper is to make comparisons between optimum, linear phase, finite impulse response (FIR) digital filters and infinite impulse response (IIR) digital filters which meet equivalent frequency domain specifications. The basis of comparison is, for the most part, the number of multiplications per sample required in the usual realizations of …
