Abstract :
Four packages of computer-graphics software developed specifically for teaching certain topics from nonlinear electronic circuits are described; namely, a package called ICAP for studying the signal processing properties of nonlinear circuits, a package called MECA for determining the driving-point- and transfer-characteristic plots of a large class of nonlinear electronic circuits, a package called GAMA for simulating the circuit models of three-terminal electronic devices, and a package called CAPPA for carrying out a phase plane analysis of second-order autonomous nonlinear systems. Several examples are presented to illustrate the application of each of these four computer graphics software packages.
