The design and development of the R-390AURR Digital Frequency Readout Unit is presented. The history of development including the techniques considered are discussed. Digital pulse subtraction, which was chosen as the most economical technique, is described in detail. The new approach to frequency readout uses the existing local oscillators of the receiver and, by a pulse subtraction process, extracts the input frequency of the receiver with an accuracy of plus or minus 20 Hz.
