This article describes the features of a DOS program that was written for interactive demonstrations of one‐dimensional (1‐D) signal processing concepts in a classroom environment. It also is used to illustrate aspects of linear systems, physical optics, and complex numbers. The program is menu‐driven, and experience has proven that it is easy to learn and use. Complex‐valued functions are loaded from a sizeable menu of options and may be processed in a variety of ways and plotted in several formats. Data files may be input from or output to other applications, e.g. spreadsheets.
