ABSTRACT:
Apparatus for generating a signal having a predetermined frequency relationship with a subcarrier includes a counter for counting cycles of said subcarrier. Count values from the counter are coupled as address values to a memory circuit. The memory circuit is preprogrammed to provide a signal having the desired frequency responsive to successive address values applied by the counter.
