Abstract

1,103,635. Pulse discriminating circuits. MARCONI CO. Ltd. 18 March, 1966 [16 Aug., 1965], No. 34957/65. Heading H3P. In television equipment, pulses of predetermined duration are selected from the composite synchronizing signal by a ringing circuit fed by the differentiated composite signal and feeding an amplitude discriminator. The half-cycle period of the ringing circuit is made equal to the duration of the required pulses so that a pulse will be provided by the amplitude discriminator following the trailing edge of each required pulse. The circuit may be used to select the first of a group of equalizing pulses.
