ABSTRACT:
Active turn-off or disabling circuits respond to control signals from a control unit which defines the mode of operation of a receiver. In response to a designation of a standby mode of operation the active disabling unit actively disables a pulse width modulator to prevent pulses from being produced based upon an input of ringing signal. In addition, the active disabling circuits prevent such ringing signal from negatively effecting pincusion protection circuits. The ringing signal is produced in a horizontal flyback transformer during a transition interval that follows a transition to standby mode of operation.
