Cool Here's the optimized code:
#include <16F876A.h>
#fuses HS,NOWDT,NOLVP
#device adc=8
#use delay(clock=20000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,parity=N)

Thanks guys! Problem solved Very Happy

for a sinusoidal input @ 1khz without offset gives 1.82, 1.66, 1.77, 1.79. Any suggestion about how to make it more solid/stable?

Wink Thanks for your beautiful answers,

By now i'm working only on the simulator so there's no noise related events.
Following your suggestions, i just have done a test.

No, i'm not saying the fuses affects the timers.
I remember you recommended other user
