Symbolic Analysis Of Electric Circuits Using TheProgram SALEC

A computer tool, the original program SALEC, for symbolic analysis of linear, lumped, time-invariant electric circuits is presented. The analysis is based on the reduced modified nodal analysis and is carried out in the complex domain of the Laplace transform. The library of circuit components, the basic circuit elements and general multiport networks specified by their matrix parameters, is introduced. The initial conditions for capacitors and inductors are taken into account. An algorithm for analysis of circuits with disconnected graphs is proposed. The program operation is demonstrated by an example.
