Abstract :
New method of estimating instantaneous parameters from sine wave samples in differential domain is proposed and studied. Performances, errors caused by quantization and by sampling delay, and application to the time-frequency distribution are evaluated. Comparison with the ordinary techniques including Prony´s method is made. The proposed method is not under constraints of the Gabor uncertainty principle, and the estimated results have ultimate instantaneousness
