I am transferring multiple analog voltage measurements through optic fibers, thus i convert the analog signal in to variable frequency (square wave pulses through V/f converter). On the receiver end i want to avoid the hardware f/V conversion and i would like to achieve this through PSOC, as i want to process these measurements without the need of the ADC. 

   

Any suggestion is much appreciated!

Thank you bobgoar.

   

 May i ask you how you calculate the frequency without an interrupt at the pwm ?

        just poll the counter capture register in main loop.
