Television.

Television as well as radio is based upon the use of radio waves.

In a television system two separate, transmitters are employed - one for the sound channel and the other for the picture channel. Each transmitter has its own antenna. The sound transmitter is frequency modulated and simultaneously transmits the sound which accompanies the image.

The image being televised is received by the television camera, which converts electrical impulses into optical impulses. These electrical impulses are amplified by the video or picture amplifier. After proper amplification the video signal modulates the high-frequency carrier of the television transmitter and is radiated into space by the aerial. The picture carrier is amplitude modulated.

At the television receiver, the picture and audio signals ore picked up simultaneously by a single antenna. Two separate intermediate frequency amplifiers are employed; one-for the picture signal and the other for the sound signal. The sound intermediate frequency signal is demodulated by a detector and, after proper amplification, by the audio amplifier. The sound signal is reproduced by the loud speaker in the usual way. The picture intermediate frequency signal is amplified by several stages and then fed into the video or picture detector, where it is demodulated.

The picture reproducing device is a cathode-ray tube. It consists of a glass envelope, a source of electrons or a gun, a control grid for varying the intensity of the electron beam and a screen. The screen is covered with a fluorescent material, which glows when struck by a stream of electrons from, the gun. A colour television has three electron guns - one for each of the primary colours - red, blue and green. They bombard a screen of phosphor dots, arranged in groups of three - one dot for each color.
