A frequency synthesizer utilizing a series of individual frequency generating circuits, each circuit containing two phase locked loops, the operation of the loops being under the control of a computer which translates the value of the desired frequency into specific digital commands for the individual circuits. In conjunction with this series of frequency generating circuits is a divider network to which the output of the last frequency generating circuit is applied. The divider network utilizes the generated range of frequencies either directly, routing them to the output, or divides the applied frequency, depending on the particular frequency to be supplied at the output.
