Fast Envelope Algorithms Using Linear Combinations of Quadrature Samples

Abstract

An algorithm for computing samples of a signal envelope from quadrature samples is presented. The method is well suited to either simple special purpose hardware or fast software implementation. Accuracy and speed can be traded off without varying the basic form of the algorithm.
