ABSTRACT:
A television bandwidth correcting system for use with a television receiver or television tuner in which the quality of the displayed picture, defined by the bandwidth of the video signal, is accurately maintained for all input signal levels. Video and audio components are extracted from the intermediate frequency signal produced at the output of a bandwidth adjusting circuit. The levels of the extracted video and audio components are compared, and the result fed back to a bandwidth controlling input of the bandwidth adjusting circuit.
