Abstract
A frequency synthesizer of the phase-locked loop type, having an output circuit circuit which produces an output signal at any of a plurality of alternating frequency values depending on the value of a command signal applied to the output circuit. The synthesizer includes a storage apparatus for storing, for each frequency value, an indication of the precise command signal value which causes the frequency to be produced. When the frequency is again to be produced the stored signal is used to rapidly drive the output circuit to produce the desired frequency
