There is always a way.

But usually the way is too f-ing hard.

Can you tell more about what you are trying to do?

If you know the wave form that you want, can you just generate the waveform you want instead of trying to filter it?

Is it true AC, or DC offset?

Is one offset positive and the other offset negative?

NO


There is a bit of DC bias among the two. One is about 2/3 the voltage range of the signal. Roughly 1 to 2.5v swing +/-

Though, they over lap about a third of the voltage range. So a window comparator is feasible but it looses a good part of the signal.

Hysteresis comparator acts goofy with the two sawtooth forms occurring back and forth.

Maybe acting on the rapid voltage rise from the one and the rapid voltage decline from the other.

I would then need a simple op amp circuit that would create a signal pending if the voltage either rises rapidly or drops rapidly. But reduces the signal if it is a gradual slide of voltage.

It would need to go high or low from the reference if spikes low/high.....I don't know.


I was hoping there is a trick or a known method of doing such.

Back to the drawing board.

I know exactly how to fix what you are saying.
But draw a diagram because you are missing pieces in your text.
