Hi!
First of all the obligatory: Long time lurker first time poster. Hope I have the thread in the right part of the forum
I'm have trouble building a switch for video signals from old game consoles. It needs to know exactly which video signals from the source is on and off.
RGB, CVBS and Y/C signals are only 0-0.7V with CVBS+CSYNC being -0.3-1.0V but I'm not certain that the channels will be entirely noise-free.
I assume the cheapest and simplest solution would be a comparator of sorts. While I do have a basic understanding of how op-amps and comparators work, unlike simple stuff such as logic gates and the 555 I have never really learned to use them correctly.
Does anyone know of a simple way to solve this?
