A Possible Procedure to Calculate Correlation Functions for the EEG

Usually, the correlation function is obtained by using pure delay elements which are difficult to synthesize on an analog computer. In this paper a calculation procedure which approximates the correlation function by a polynomial is proposed. This procedure, based on an identification method developed by Izawa and Furuta ll, does not require any pure delay element but rather a bank of simple filters.
