Abstract
Methods and electronic apparatus for recovering relatively high-resolution information from a partial wave representation of an information signal. According to the invention, there is provided a method of operating on a given partial wave function, or of producing a partial wave representation of an information signal as part of the method. Portions of the partial wave representation of the information signal are synchronously selected as by signal sampling under control of an interpolated high frequency clock. An inverse partial wave representation of the selected portions of the transformed signal is then performed, and the inverse partial wave representation is linearly deconvolved to produce a high resolution equivalent of high-resolution information signal. The invention may include an analytic converter for removing the effects of any dispersion of the partial wave representation. While the concepts involved are universally adaptable to signal processing systems, preferred embodiments of the invention as applied to a modem network and to an interferometer are described.
