Hello, I will need some advice from you. I am making a frequency counter, the circuit is meant for displaying the rpm or speed in a car.
The speed and rpm have an amplitude of typically 5v, but I have seen 12v in some cases. The signals are counted with the help of a pic16f controller.
What are the alternatives for a signal processing circuit? The frequency is typically in the low kHz range.
