The Production and Utilization of a Synthetic Sampling Frequency as Applied to Quadrature Demodulation for Envelope Detection

Abstract

A synthetic sampling frequency has been developed utilizing a 25 kHz SERVO-channel CW signal and a predetermined frequency of choice to achieve the proper sampling frequency for quadrature demodulation. The required synthetic sampling frequency examined here is 4f and is compared with the actual pre-recorded 4f. Very favorable results are shown for signals which were envelope detected utilizing quadrature demodulation methods. This technique may be applied to produce any sampling frequency of choice, and can thereby prove to be a valuable signal processing tool.
