Several symbolic mathematical programs have recently become available on a wide variety of machines. This paper describes the implementation of basic signal analysis and transforms for DSP with one of these systems known as Mathematica. By extending its capabilities through a proper representation of knowledge of discrete signals, operators, and transforms, Mathematica can take the forward and inverse z-transforms symbolically and apply the DFT as a symbolic summation.
