Abstract
Abstract The synchronisation pulse separator, for recorded composite TV Signals, has the composite signal passing one way directly to a first MOSFET changeover switch and the other way via a clamping MOSFET switch to the second input of the first switch. The first switch is controlled by the blanking pulses and its output contains the composite signal minus the synchronisation pulses. The control signal for the clamping switch is derived from the composite signal. The advantage lies in the cut-out level for synchronisation pulse separation being easily set and stable.
