It can be regarded as the adaptive approximation of its complex exponential signal model to the dynamic phasor of an oscillation over a finite time interval. Equipped with a closed signal model, it is possible to implement it in one cycle. In its first adaptive stage, it estimates … WebNext, Prony basis functions, which are exponentially decaying cosine waves with phase delay and variable amplitude, are described as potential objects to be used to approximate a given impulse response function. Then it is shown how a superposi- tion of Prony basis functions can be directly mapped back to an equivalent linear state-space model. heritage hair brush
