hi
i already built a zero cross detector using the IC LM311 ,and the circuit is based on a schematic on www.national.com on conventional positive feedback .
the problem is the sine wave change when i turn on the zero cross detector. does this effect the accuracy of the data i am taking? if it do, how do i fix this problem .
any advice is appreciated,thanks
