ABSTRACT:
A system for suppressing signal disturbances, which are due to switching from a first television signal to a second television signal, for use during a playback of the television signals on a magnetic tape recorder and in connection with an electronic switch for disconnecting the first television signal and connecting the second television signal to output terminals of the switch includes a delay line coupled between a demodulator and a timing error corrector for receiving and delaying the demodulated signals for a time substantially equal to a line period. Additionally, a switching sub-system is coupled to the demodulator for receiving and demodulated signals and the delayed demodulated signals, and for switching for a period of time substantially equal to the line period to generate another output signal from the demodulated signals; furthermore an amplitude filter is coupled to the switching subsystem, and the timing error corrector for receiving the output signals, and selectively passing synchronous signals, forming a portion of the output signals, to the timing error corrector.
