SYSTEM AND METHOD OF EXTRACTION OF SINUSOIDS OF TIME-VARYING CHARACTERISTICS

摘要

A signal processing technique and an apparatus built on the basis of such amethod aredisclosed. The present invention provides means of extraction of a more orless specifiedsingle sinusoidal component of a given time-varying signal, which may bepolluted by noiseand undesired components, and tracking variations of amplitude, phase andfrequency ofsuch a sinusoid over time. It also directly provides estimates of time-varyingparametersof sinusoidal component of interest such as amplitude, frequency and phase.The signalanalysis/synthesis tool of the invention, when used as a complete system inits own or asthe fundamental building block of single-core or multi-core systems, findsapplications indiverse areas of engineering and science.
