Hey gentleman!
Hi
When your input signal will be at zero , your zero crossing circuit will have output. for example a differentiator circuit can be as a zero crossing circuit( part of that).( if you give an square wave to your differentiator circuit, its out put at zero point will be spike . if you want a zero detector , you can give your signals to the comparator or op amp , without feed back , and your out put will be square wave as well as , and then you can get differential from that and you can rectify it ( with bridge) . ok your zero detecting circuit is ready to use!
Best wishes

Hey Buddy!
Hi
What do you need? i think that you wanna know that what is the application of zero detector . if yes : the differential of each function at maximum will be zero. ok with the zero detector circuit , we will can find the peak of each signal . or we can use that for synchronization or we can use that for phase analyzing . for example we give a sinusoidal wave to the simple filter, we want to know that when the phase margin will be variable . with zero detector we can guess the phase margin as well as
