Abstract:This article presents a method for improving the nonparametric frequency estimation of the fundamental periodicity of a multifrequency signal when a smaller number of periods are covered-up to two periods in the measurement time. The estimation procedure uses the weights of two Rife-Vincent I (RV1) windows on the same set of acquired signal samples and then uses a combination of two consecutive discrete Fourier transform (DFT) amplitude coefficients in the quotient. To reduce the harmonic influence, the techni… Show more
