ABSTRACT:
A bidirectional pulse generator suitable for driving a video disc stylus deflector transducer. A differential amplifier is arranged with both its inverting and non-inverting input terminals connected for receiving a prescribed pulse waveform. First and second diodes are respectively connected between the inverting and non-inverting input terminals and a point of bilevel potential for selectively conditioning one or the other of the diodes to conduct, thereby establishing the quiescent output potential of the amplifier and concurrently shunting the pulsed waveform from one or the other of the amplifier input terminals.
