The television signal generator composed of a game RF modulator and a piece of CMOS integrated circuit is shown as the chart. In the Figure: Schmitt triggers Al ~ A4 and RC components form the line sync, horizontal, vertical, and audio signal oscillator. S is used to select the horizontal, vertical signal. A5 and differential circuit C5, R5 will shape the line sync signal in 5 ~ 7μs positive narrow pulse, which will be sent into the RF modulator with horizontal, vertical signal. The power can use the 6V cascading battery.
