Abstract

959,695. Television. PYE Ltd. May 15, 1962 [May 15, 1961], No. 17592/61. Headings H3T and H4F. A transistor TRI acting as a television synchronizing pulse separator for signals applied to the base via resistor R6 from the cathode of valve V1 has its base bias network R7, R8 returned to the anode of valve V1 in order that the level of the bias may change when the current through valve V1 changes, consequent upon a change of video signal amplitude, whereby the portion of the video waveform which drives the transistor into conduction bears a substantially constant relation to the black level. The circuit is otherwise similar to that described in Specification 959,694.
