I am new to circuit design so forgive my question if it sounds silly. I am just playing around with some ideas but I was looking at some schematics for a zero crossings detector. Can a two input 'and' lojic gate be used for this type of circuit? Have one input tied to ground. The other input would be tied to a low voltage ac power supply. Then when the ac voltage crosses zero both inputs to the and gate would be zero and would therefor provide a high output. Or am I missing something? Thanks in advance for any feedback i may receive.
