Measurement Techniques Aims and scope

Abstract

A high-speed method of estimating the instantaneous frequency of broadband signals with slowly varying amplitude and phase using a short sample in real time is proposed, and results of numerical modeling of the measurement procedure are presented. The speed of response and noise immunity of the method is compared with the existing method, based on the theory of signal “splitting.” It is shown that in both methods it is possible to use recurrence relations, which considerably reduce the measurement time.
