SIGSYS — A SIGNALS AND SYSTEMS INTERPRETER

Abstract SIGSYS is an interpreter that has been designed to generate, manipulate and display time and frequency signals. It runs on PC's or compatible computers and has a powerful and versatile command language in the MATLAB style. The supported data types are real and complex scalars, real and complex signals and polynomials with real and complex coefficients. The capabilities of SIGSYS include a grammatical structure for the solution of sets of differential equations. In spite of its power, the SIGSYS command language is easily learned and allows the user to concentrate on the manipulations and calculations.
