Title: Improvements in or relating to television receiver circuit arrangements
IPC: H04N5/12
Filed: 1962-04-11
Abstract: 979,924. Sawtooth and pulse generating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 11, 1962 [April 14, 1961], No. 14006/62. Heading H3P. [Also in Division H1] In a television receiver, flyback pulses for controlling a phase comparison stage are derived from the e.h.t. secondary winding of the line output transformer via a capacitive coupling. The leakage induction between e.h.t. secondary and primary windings is tuned as described in Specification 723,510 so that the current through the leakage inductance at the beginning and end of the flyback period and the derivative of that current are substantially zero. This minimizes spurious oscillations during the forward stroke of the sweep. As shown, the flyback pulse is obtained from a plate 12 mounted on the outside of the e.h.t. secondary winding 8 of the line output transformer. A heavily damped resonant circuit 17, 19 tuned to the fundamental frequency of the flyback oscillation, provides the waveform shown, which is used to control a phase comparator.
