Abstract

Strip filters select the portion of a signal having energy in a strip shaped region in the time-frequency plane. They are linear, time varying operators capable of recovering a class of transient signals which are linearly separable in the time-frequency plane. The Hermite function method and the elementary operations method are two approaches to implementing strip filters. A strip filter is used to successfully recover a finback whale sound. The design of discrete time strip filters can be viewed as an operator approximation problem.
