Abstract
A digital frequency synthesizer includes a phase locked loop having dual presetting means for enabling the loop to generate a first frequency signal (e.g., 'transmit' signal) for each of many selectable channels and generate a second frequency signal (e.g., 'receiver' signal) in the form of the first frequency signal set off by an intermediate frequency (e.g., IF frequency) and programmable means for varying the frequency offset.
