These software filters replicate the signals that consoles output to the TV. They vary in quality, with the lowest quality being RF, then composite, then sS-video Video, and then RGB (scartSCART) being the highest quality. Many emulators have blargg's NTSC filters filter libraries<ref name="blargg">http://slack.net/~ant/libs/ntsc.html</ref> built into them. They can also be separately downloaded in filter plugin format.
