Abstract
A vertical synchronizing circuit wherein noise pulses or signals which may accompany vertical synchronizing pulses are locked out for a predetermined time subsequent to the receipt of a vertical synchronizing pulse is shown. A counter counts pulses at the horizontal or line deflection rate. At a particular count of the counter the vertical synchronizing circuit is conditioned for receipt of a vertical synchronizing pulse. Subsequent to the receipt of a vertical synchronizing pulse, the vertical synchronizing circuit is conditioned to be unresponsive to any received pulses until the counter again counts to the predetermined count.
