rpm to voltage conversion circuit
Yes,
there is other solution with a frecuency-voltage converter (LM-2917). But I need a ac signal (voltage) and that signal is in the car's coil and i need measure the rpm from the battery
Thank you
hello,
I want to to measure the rpm car motor from the ripple battery. These ripple is related with the rpm motor.
I think to use a hp filter for to amplifier the ripple and cut the continuos signal.
I hope that you Know the best solution
