12f675 programming question

o.k if i understand you want to measure the amplitude of an incoming frequency right?

in this case a/d conversion time will gives you some crazy results. Also it depend on which part of your frequency cycle the A/D take the voltage measure too... so in this case you can monitor and compare few reading and take the highest one BUT

I suggest you to convert frequency to voltage. You can do it simple with an OP-AMP as a full-wave rectifier and put an capacitor to the output to get *clean* voltage.
