Abstract :
Overlap Resolution signal processing utilizes residue-like arithmetic and opens up a powerful approach to parallel analog computations with digital accuracy. This new redundant representation of signals, with Continuous Valued Digits, carries the accuracy of analog signal processing beyond the accuracy of the analog circuitry itself. The proposed processing methodology can also be applied to a digital system. Presented tolerances for analog digit circuits and the required digit word lengths for digital circuits show the practical feasibility of Overlap Resolution
