I have a RGB signal comming from a device that has the voltage level too high for the signals (i think about 2Vpp instead of 750mVpp) and i'm using a voltage divider to drop the voltage to the appropriate levels and then send the signal to an encoder and straight to a RGB table to be used on a RGB monitor (to have RGB encoding to NTSC and direct RGB out at the same time).
I've tried multiple configurations for this, but nothing yet has gave me the results I want (perfect encoding and perfect rgb pass through).
Exactly what configuration do I need to make this work? Something like the first circuit or something like the second circuit? Or something completely different? Where exactly do I need to ac couple the signal? In the places I have the capacitor already?
BTW, the op-amp that im using is the AD8054, which is designed for video signals so I know im using the right kind of opamp for this application.
