Television System

The television system is considerably more complex than the sound broadcasting system. In a typical television system two separate transmitters are applied, one for the sound channel and the other for the picture channel. The sound transmitter is frequency-modulated and at the same time transmits the sound which follows the image¹. Each transmitter has its own² antenna.

The image which is being televised is received by the tele­vision camera, which converts³ the optical image into electri­cal impulses. These electrical impulses are amplified by the vi­deo or picture amplifier.

After proper amplification, the video signal modulates the high-frequency carrier⁴ of the television transmitter and is ra­diated into space by the aerial. The picture carrier is ampli­tude-modulated.
