1. A method of equally reducing noise in measured signals, comprising the steps of: a) determining a relative value in noise variance at each of the measured signals based upon a function of a predetermined noise model to generate a noise-model based variance; b) automatically generating a discrete filter kernel of a noise-equalizing filter for each of the measured signals based upon the noise-model based variance; and c) applying the discrete filter kernel to a corresponding one of the measured signals to generate a filtered measured signals.
