Another Excel abuser

Years ago when I used to train broadcast engineers in analogue TV, I needed a way to show how RGB gets changed to YUV - loses or gains levels and then gets changed back again to RGB in TVs - I could not afford signal generators, coders, processing and waveform monitors, but excel was great as a way to show multiple waveforms and with slider controls I could vary levels.
