Hello Mister_e,

M>>Be sure that your signal input have at least close to 3.5 volt peak of amplitude for great result.<<


Thanks Mister_e... I was kinda leaning in those directions, but was not sure which would be better. I did not know what the PULSIN would consider as "ON State" Since we have a sign wave, I did not know whether you had to a certain "voltage" for the PULSIN to be triggered as on (Other than the minimum operating voltage of the chip).

I am assuming the PULSIN measures the entire wave, from positive to positive, and the RCTIME measures only 1/2 of the wave. And the PULSIN will operate on the upslope of the sine wave, Is this correct?
