Abstract

847,619. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 18, 1957 [Jan. 21, 1956], No. 1936/57. Class 40(3). In an arrangement for separating line and frame synchronizing signals from video signals the composite signal, which is derived from a valve 6, is supplied to a valve 11 operated as a peak detector to derive the separated synchronizing signals 26 of the anode thereof. In accordance with the invention, the clipping level of valve 11 is varied in accordance with variations in the contrast control 13 by connecting the screen grid of valve 11 to the screen grid of valve 6 so that variation of control 13 automatically adjusts the clipping level of valve 11 in accordance with the amplitude of the signals.
