[LAD] Fwd: Measuring phase and frequency response of a filter.

[Bill Gribble]

How are your filters implemented?  If they are biquad or other similar
type that you can easily express as Z-plane poles and zeros, it's pretty
easy to generate a graph of the phase and amplitude response from the
locations of the poles and zeros. 

Typical link:
