Hello all,
I am primarily a software person, but I find myself in the hardware world as of late. Please forgive what maybe a newbie question.
I am trying to build a circuit that can detect a specific frequency from the following frequencies: 128kHZ, 129kHZ, 130kHZ, 131kHZ and 132khz.
If the frequency is detected, I would like the ability to pull up the voltage on a specific data pin.
only one of the frequencies will (should) be activating a ferrite core inductor at a time.
I have looked at band pass filters and have not sussed out exactly how I would implement this.
any help pointing me into the right direction would be greatly appreciated.
Thanks for the time,
Bassguy1965
