  • Circuit arrangement for extracting a field synchronizing signal from a television synchronizing signal
    Patent number: 4414570
    Abstract: A circuit arrangement for extracting a field synchronizing signal from a television signal comprising binary switching stages. Herein, the duration of a broad field synchronizing pulse is determined because the peak value thereof is sampled with a clock signal, the period of the clock signal being significantly shorter than the duration of a line synchronizing pulse. For this purpose the frequency thereof may be the color sub-carrier frequency or a multiple thereof.
