Damped-amplitude & polynomial frequency model for short-time ambient vibrations of a building

Abstract— In this paper, we give estimators of the frequency, amplitude and phase of a noisy sinusoidal signal with time- varying amplitude by using the algebraic parametric

The proof is given that in a symmetric double well model of the symmetric H-bond with damped stretching mode, there is no asymptotic-time symmetry breaking owing to a full..

The model was used to predict the effects of modulation rate, depth, stimulus duration, and modulation phase on FMDTs in the presence of an AM masker on the sole basis

Results on simulated signals show that the proposed algorithm is more efficient than the algorithm based on polynomial amplitude models, and allows the estimation of
