Abstract

PURPOSE:To produce the vertical blanking pulse synchronized with the flyback time of the vertical output, by utilizing the vertical pulse and the horizontal pulse or its double-frequency pulse at the vertical driving stage. CONSTITUTION:With the fall of the vertical pulse in front of the back edge of the horizontal pulse PH, the output A of the F/F has a fall by the pulse PH. And the reset signal of the latch circuit becomes 1 with the pulse PH arriving next, and thus the latch output OUT has a fall.
