Linear systems analysis program

The computer program LSAP (Linear Systems Analysis Program) is an interactive program with graphics capability that can be used for the analysis and design of linear control systems. Nearly all classical design tools are available, including manipulation of transfer functions and generation of root locus, time response, and frequency response plots. The program is capable of working with both continuous time systems and sampled data systems. For continuous time systems, the Laplace transform is used, and for sampled data systems, the -transform is used. The capability of converting from a Laplace transform to a -transform is provided.
