In this paper, we consider an extended form of the optimum sub-band interpolation for a family of band limited signals. It is assumed that this family of signals is a certain subset of the set of the signals whose Fourier spectrums have weighted L2 norms smaller than a given positive number. We use the sample values of the output signals of the finite number of linear systems excited, at the same time, by a band limited signal to be restored approximately. The proposed method minimizes the measure of error which is equal to the envelope of the approximation errors in the frequency domain. It is proved that the presented method is the optimum, in a certain sense, among all the linear and the nonlinear approximations using the same sample values of the signal.
