Patent

CA 2349041

A signal processing technique and an apparatus built on the basis of such a method are disclosed. The present invention provides means of extraction of a more or less specified single sinusoidal component of a given time-varying signal, which may be polluted by noise and undesired components, and tracking variations of amplitude, phase and frequency of such a sinusoid over time. It also directly provides estimates of time-varying parameters of sinusoidal component of interest such as amplitude, frequency and phase. The signal analysis/synthesis tool of the invention, when used as a complete system in its own or as the fundamental building block of single-core or multi-core systems, finds applications in diverse areas of engineering and science.
