| Abstract: | Summary Minitools are software tools that have been especially designed and implemented for use in education and on small industrial problems. They offer limited capabilities if compared to full-grown commercial systems but are much easier to learn and to use. Three such programs are introduced in this paper: DESolver for differential equation solving; Frequency for frequency response analysis and design; and BDE Sim for simulation and frequency response analysis from block diagrams. BlockSim, which is more a tool for implementation than a minitool, is also presented briefly. The four programs run on Macintosh and IBM compatible PCs. All programs are in the public domain; on the IBM PC a GEM desktop is needed to run them. |
