Hello,
I'm attempting to convert a received signal frequency to voltage for a comparison/subtractor with the sent/original signal (I've a linear ramp oscillator). From the datasheet of the LM2917 f/v converter I know that Vout= Fin* Vcc*R1*C1.
If my original signal is about 4.2V (Vp-p), to which Vout should I design the circuit?
Ultimately, in the comparison stage, I need the voltage difference between the original signal and the one received (maybe I should have a subtractor?) in order to measure distance.
Thank you.
