Abstract
Synchronization signal separator circuit for television receivers, characterized in that it comprises an electronic valve equipped with at least three electrodes, in which its control grid is connected to a video signal source, selected among the various points of the corresponding channel , through a time constant circuit, said valve being polarized so that it only conducts when the instantaneous values of said video signal reach the amplitudes corresponding to the synchronism pulses, passing to the blocked state and interrupting, consequently, the passage of current through the anodic output circuit of the separated synchronization pulses, when said values descend to the level of amplitude corresponding to the image signals.
