In this article. an improved version of three state-of-the-art interpolated discrete-time Fourier transform (IpDTFT) algorithms for the estimation of the frequency and the damping factor of noisy damped sinusoids is proposed. Sinusoid amplitude and phase are also estimated. Improvement is obtained by both compensating the effect on the estimated parameters of the spectral leakage from... https://www.fitnessgravesyardes.shop/product-category/handrail-end-cap/
