    Corrupted Sine wave on zeroo crossing

    Re: Corrupted Sine wave on zero crossing Thanks Brian my problem is corrupted 50Hz sine wave is superimposed with harmonic of 5th order and pic 16f87 cannot find the zero crossing. where to connect the low pass filter before zero crossing pin? at the moment there is a 220k resistor from...
