Sonic on an oscilloscope

This is a demonstration of the experiment with synchronizing a TV-signal with an oscilloscope. I used the Sega Gopher portable console to generate a composite signal, than fed it to a simple circuit using TI LM1881 Video Sync Separator chip and OpAmp-based inverting amplifier for the Luma signal. The sync separator is the key element. It can generate HSync and VSync pulses from a composite signal, so I just had to add some passive RC integrators to generate sawtooth waveforms for horizontal and vertical swe
