Abstract :
Experimental verification of the functionality of a novel method of detection, extraction and estimation of amplitude, phase and frequency of sinusoids of time-varying nature is presented. A set of nonlinear differential equations governs the dynamics of the algorithm. The proposed algorithm has been digitally implemented on a digital signal processor (DSP) platform and the laboratory verification of its performance is presented. The algorithm has a very simple structure which renders it suitable for implementation both on hardware and software platforms.
