Hi team:
I have to make a circuit to measure the frequency of a square signal (0V - 3.3V). The previous step is introduce the signal to an optocoupler and get the same frequency output signal, (I only care about the frequency because a high accuracy is needed)
What optocoupler do you think is good for this purpose when the signal goes from 100 Hz to 10 KHz?
Thanks
