Are you wanting the output to be proportional to the difference? The comparator approach is a thumbs up or thumbs down, 0 or 1, essentially digital output. If you need proportionality, you'll need op amps. A difference amplifier. You need to provide more detail for anyone to help you further.How would i make an analog circuit that can produce an output signal upon the intersection(where they are of = voltage) of 2 waveforms
Maybe not. What will be producing the low Hz wave? To most audio, that looks like DC and won't be passed through most pieces of audio equipment.... my main question here is, Is this possible?
Here's the same simulation, but the 100Hz In signal was reduced to 20Hz so you can see the output transitions more clearly.
Critical information, thanks for making it clear. Next time, put it in your first post to get higher quality responses, like the circuit proposed.It seams to me like no one is visualizing the goal of this circuit.
It is meant to produce a constant stroboscopic effect on the speaker cone making it appear to oscillate in and out slowly.
