TELEVISION RECEIVER FOR RECEIVING A PICTURE CARRIER WHOSE AMPLITUDE IS MODULATED WITH A VIDEO SIGNAL, AND A SOUND CARRIER WHOSE FREQUENCY IS MODULATED WITH AN AUDIO SIGNAL

摘要

PHN. 9624 12 Television receiver for receiving a picture carrier whose amplitude is modulated with a video signal and a sound carrier whose frequency is modulated with an audio signal. The sound intercarrier signal produced by a mixing circuit is divided by a detected amplitudemodulated interference wave, a signal of a substantially constant amplitude being thus produced. A limiter preceding the frequency demodulator is consequently not required.
