description A method for extracting predetermined types of electrical signal data from an overall composite of time analog signal input information, the method consisting of constructing an ideal filter for each of selected electrical signal components of an input signal group, such filter construction being carried out by determining the pseudo-inverse or generalized inverse of a polynomial matrix as determined for the particular input signals to be examined, with application of the polynomial matrix for preadjustment of a multichannel pattern discriminating filter which, when energized by the input signals under examination, will produce separately the requisite selected electrical signal component outputs. Apparatus for carrying out the method may consist of plural channels of time domain filters connected in series with a weighting device for convolving input electrical signals; each of the convolution filters is adjusted to function at predetermined times and amplitudes in accordance with the matrix function or operator determined for selected signal component functions of a particular set of input electrical signals.
