Square wave signal with ADC converter

Postby tnnelectronics » Thu Mar 01, 2018 11:51 am

I have a 7Hz 5Vpp square wave signal, you give me an advice on an easy way, to turn that signal into the corresponding DC voltage, so I can read it through the microprocessor's ADC converter?

Thank you.

Do you want to just detect the presence or absence of this signal? Or a voltage corresponding to frequency, peak pulse voltage, or mark-space ratio?
