Abstract

PURPOSE: The gate circuit is installed at input side of 1H-delay line, and is controlled only during burst period by supplying gate pulse. At the same time, the burst signal which is supplied to 1H-delay line is intercepted or reduced. Thus, picture quality deterioration can be prevented.
