[sdiy] Piecewise filter

[Ian Smith]

Hey all,

Just had an odd idea (when don't I?). I've just about finished my college algebra class (it's been 7 years since I've done serious math... bit rusty), and we covered piecewise functions recently.... where the graph acts one way until x reaches a certain value and then it changes behavior. So, what if a filter did that? say be a lowpass until the signal or a CV reaches a certain voltage and then change to a highpass or bandpass or any combination there of.
