SIMPLE_VIDEO_LINE_BAR_GENERATOR

A 555 and a dual 556 timer generate a rudimentary video signal, as shown in the schematic. The first timer generates 4.7-μs synch pulses operating in the astable mode with a 64-μs period. The sec-ond timer generates a delay pulse, which triggers the third timer to generate a bar. The second timer sets the bar position and the third sets the bar width.
