IIR Digital Filters

IVEN the simplicity and stability of the FIR filter, why would you ever want to consider
using an IIR filter? This issue has been debated over the years in numerous articles,
papers, and book chapters in the DSP literature. The short answer to the FIR versus IIR
question can be distilled down to two brief points.
1. There is a tremendous amount of analog filter design knowledge available and, as

2. To meet certain filter design specifications, very high-order FIR filters ...
