I would try a DSP proto board.

1 Digitize

2 Look during a sampling window for rising or falling trends above backgroud, while save raw samples too.

3 Subtract extracted sawtooth from matching raw sample.

4 Send difference result to an D/A converter.

5 Watch cat videos

Eh, I guess I do need to cross into digital at some point.

After all, a comparator is pretty much a 1 bit digital signal.

Maybe a set of logic gates to produce a result from low bit flash ADC. Enough to allow a true (1) if the sequence goes from binary low to binary high and none in between, visa versa.

After the flash ADC circuit, lets example 2 bit. 4 possible combinations. If the results go 00, sample and hold, if that sample is 00 and the next binary is 11, then the output is high and left channel. But if it goes 11 then 00, same but right channel. If any other, 00 then 10, clear and repeat.

Idk, hard to say in thought. I could run and grab some 7400 gate IC's but....maybe.

I like to get it all done in analog (and simple flash like ADC) before having to incorporate processing and programming.

But I will investigate your suggestions. Thanks.

If I get it to work, I'll be sure to post up.
