QuickSig-an object-oriented signal processing environment

An object-oriented DSP (digital signal-processing) environment called QuickSig is described that is based on recent developments in object-oriented programming (New Flavors on Symbolics Lisp machines). The design philosophy of QuickSig has been to extend the Lisp language by a layer of general DSP constructs, abstracts, and structures like signals, filters, windows, graphical presentations, and related signal-processing operations. QuickSig is a fast prototyping system for algorithmic development. It is extendable to include new ways of modeling signals and signal processing, both numerical and symbolic. The main features of the present system and some features that are under development are reported.<<ETX>>
