The use of signal properties for signal representation. (English) Zbl 0304.94004

Summary: An efficient procedure for signal representation, based on known signal properties, is presented. The representation minimizes the maximum of the ratio of the error and the signal norm, the per cent error. Signal classes are specified by normalized quadratic functionals. These results are contrasted with the theory of \(n\)-widths of signal classes, and several applications are developed.
