[quote:Anonymous Coward 2086060:MV8zNDY4MjI3XzYyMDExMTc3X0U5NkQ3NkQ5] [quote:-Adam-:MV8zNDY4MjI3XzYxOTg4Mzc4XzFDQTlEOTg4] I was thinking about a sample and hold circuit and compare the prior reading with logic. No circuit will help the question.... Have an alternating saw tooth. Need to filter the difference from each other. I COULD go the Arduino route and filter with software but I have a liking for avoiding binary applications when possible. Except for flash ADC. [/quote] Capacitors are your friend. [/quote]
Original Message
Is there any way to separate or filter out a sawtooth wave dependent upon which direction the saw tooth edge is?
ie, one part lead rises sharp and tapers for one signal and the other signal has a leading taper then a sharp drop in voltage.
I do not want to filter frequency, already have a passive low pass to cut high freq noise.
Just need to separate the two signals. (or omit one and then buffer, omit the other)
I am completely baffled on this one.
