ABSTRACT:
A television synchronization generator has a clock generator driving a ROM. The ROM has stored in it the required sync signals. In order to conserve the ROM size, the ROM is addressed by a counter except during portions of the sync signals when the amplitude remains a constant. During these portions the counter continues to count.
