I am sure that someone will find this dumb. I have a circuit that is grounded via a bridge rectifier to my mains supply. Thus it is in fact live and an earthed circuit. If you were to connect these grounds together one or both will fuse. What I need to do is pass a video signal from the earthed one (PC) to the live one (TV without this facility). I have found the connections on both circuits but I need a way of safely connecting them. I have though of using some kind of transformer though I can’t seem to find such. Would it work if I made use of two capacitors (one on ground and one on the signal) to interface these devices or does someone know of a proper way to do this.
Very much appreciated.
