Abstract
A network of filter elements for transforming an analog signal of infinite bandwidth into a discrete filter space representation having a bandwidth equal to .pi.. In one embodiment the filter network includes Laguerre filter elements. Other embodiments include methods for estimating the values of the amplitudes, frequencies, and phases of the frequency components of the analog signal, for reconstructing an input signal, and correcting for non-ideal filter elements.
