Abstract

PURPOSE: To secure an automatic setting of the frequency characteristics to a constant level and thus to prevent the deterioration of the picture quality resulting from the difference of the tape characteristics and the dispersion of the head, by comparing the reproduction output of the head with every field and then controlling the characteristics of the equalizing amplifier.
