ABSTRACT:
A decimal frequency synthesizer in which, for each decade, two identical sets of four arithmetic progression frequencies are generated by programmed frequency divisions effected in parallel from a standard frequency and applied to two mixers. The first mixer further receives the frequency from the preceding decade and is followed by a divide-by-2 divider, whereas the second mixer is further receives the output of said divider and is followed by a divide-by-5 divider.
