Pretty funny because I was just thinking about implementing a state<br>
variable filter this morning. Truth is I'm looking for a generic/not too<br>
expensive filter whose source code is easy to find (mostly for quick<br>
tests and benchmarking). And that I wouldn't spend 4 days coding :)<br>
<br>
Would that be a good pick ? any other suggestion ?<br>

That's the basic stuff, works smoothly if you understand the limits (e.g. stability as you approach Nyquist). Obviously, if you want character you need to look elsewhere (e.g. Tony's DSM).<br><font color="#888888">
