this sensor varies frequency based on air passed by so it starts at 25-50hz and as engine speed increases so does the frequency, up to 1800hz. anything above that and it hits cutoff so i need to keep it at 1800hz.it does need to stay a square wave though.
I truly appreciate the replies. I must admit though that I am getting a little lost. Do you guys know where I can find a starting point for this thing. Basically this a mass air sensor varying freq. from 25 to 1800hz and I am just trying to build a circuit to clamp it off at this 1800hz freq. It...
I am looking for a circuit to help me clamp off a 5 volt square wave at 1800hz. I have tried a few different things but I cant get it to work properly. Any help would be greatly appreciated.Yes I am a little new to this.. LOL
