A frequency translator receives an input frequency signal and an offset frequency signal, and processes the signals digitally in order to obtain an output from a multiplexer. Pulse trains derived from the input frequency are provided to an N-bit shift register. The outputs from the shift register are provided to a multiplexer which is controlled by count signals from the offset frequency. The multiplexer provides, as its output, a single sideband output at a frequency equal to (fc-fos)/N, or (fc+fos)/N.
