Help! - circuit compared two RF freqs & triggers when same
The idea is compare a FIXED RF signal (any where from 455Khz to 12 Mhz at least, more range the better) with a sweeping Frequency (RF signal of fixed voltage). The idea is when they are the same, it triggers a pulse to the Z intensity input of the scope.
I NEED HELP with the comparator and trigger. I have zero idea and hoping a few IC's will do it.
