N2 - Estimating evoked potentials is a process of detecting a signal out of measurements ensemble. The evoked potentials are usually described as a deterministic process which is corrupted by unrelated noise. The signal is usually detected by averaging these measurements. We propose an improved consistent estimation of the signal, which is based on the average response. The proposed filter is depend on the estimation of the signal and the noise autocorrelations. The filter coefficients are obtained by minimizing the mean squared error (MSE) of the optimal filter of a non stationary process applied on a single sweep. The average and autocorrelation matrixes can be build in real time, without saving the measured data. A short off line processing of the calculated data is needed afterwards.
