Modeling of evoked potentials as decaying sinusoidal oscillations by PRONY-method

The averaged transient evoked potentials (EPs) have been modeled as a sum of damped sinusoids. The Prony method has been used to estimate the parameters of the damped sinusoids. This approach represents the signal more efficiently when compared with the FFT and autoregressive (AR) spectrum estimation methods. The results obtained are intimated with the cellular level findings.
