I have some questions about the difference among various IIR filter architectures. The architectures concerned are: DIRECT-II, CASCADE, PARALLEL, NORMAL, WAVE, LADDER. 1) Is there a difference in frequency response? 2) How about speed? 3) arithmetic roundoff error? 4) coefficient roundoff error? 5) Which is the most popular? And how are they being used? Answers for one or more of these questions will be greatly appreciated. Private mail welcomed at mchung@ee.tamu.edu Thanks in advance. Maranatha
