Задание №4

The television transmitter sends out special signals. They are sent out in addition to the picture impulses. The signals synchronize the picture at the receiver with the picture picked up by the camera.
At the television receiver the picture and audio signals are picked up simultaneously by a single antenna; the voltages induced in the receiving antenna are fed into the radio frequency stage of the receiver; and the picture carrier and the sound carrier are converted into two separate intermediate frequency signals. One signal corresponds to the sound carrier and the other to the video or picture carrier. Two separate intermediate frequency amplifier channels are employed; one for the picture signal and the other for the sound signal. The sound intermediate frequency signal is demodulated by a detector. 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 having wide-band frequency characteristics and is then fed into the video (picture) detector, which appears in the output of the detector is then amplified in the video amplifier, which corresponds to the audio amplifier in the sound receiver. Only it must pass a much wider range of frequencies.
