PIPELINE SIGNAL PROCESSING WITH HIGH RESOLUTION IN BOTH TIME AND FREQUENCY DOMAINS

Abstract

An algorithm for real time signal processing with high accuracy of determining both frequency and time characteristics
of RF signals is proposed. The algorithm provides frequency resolution through FFT processing and pulse width measurement in time domain. The algorithm is developed for real-time systems, for example in laboratory measurement devices or in radioemission monitoring applications.

Keywords: signal processing, frequency measurement, pulse width measuring, real-time processing
