Invert PAL signal




Dear Friends,


I want to invert a PAL S-Video ( or CVBS) then recover to original signal.

Inversion will be relative to the time axis.

I mean I want to change the positive voltages to negative and negative.

Then I want to change negative to positive and positive to negative.

The two parts of the circuit needs to be seperated.

Thank you for your interest.

Regards.

A simple common emitter single transistor amplifier will do the inversion (and a second one for reinversion).
So too would a dual video operational amplifier.
The above assumes you have enough electronics (and soldering iron) experience to do this.
