SIGNALS v4.00 was developed to illustrate signal processing concepts in graduate level courses. It has a large number of built-in functions such as Sin, Sinc, Rect, Gauss, Tri, etc. These are used to build up a real/imaginary array that is processed by operations such as Add, Multiply, FFT, Convolve, etc. The results can then be plotted in various forms such as Magnitude/Phase, Real/Imag, and Argand. The one-key menu operation makes the program fast enough to use in a classroom environment. Results can be stored and retrieved in several file formats. The program can be run under Windows.
