TITLE OF THE INVENTION Line Sampling Circuit For Television Receiver ABSTRACT OF THE DISCLOSURE A composite synchronizing signal during a vertical blanking interval includes horizontal sync pulses, equalizing pulses and vertical sync pulses. A line sampling circuit includes a vertical pulse gate which detects and filters an been number of vertical sync pulses, a flyback pulse gate which filters the flyback pulses sequentially after the vertical pulse gate has filtered the even number of vertical sync pulses, and a 5-bit binary counter which counts the even number of vertical sync pulses and the flyback pulses. The line sampling circuit further includes a line decoder which produces a signal after the 5-bit binary counter has counted the even number of vertical sync pulses and a predetermined number of flyback pulses for sampling a particular line defined between the neighboring horizontal sync pulses pro duced during the vertical blanking interval. -1-
