Constructionof symbolic functions for active electric circuits using the method of short-circuiting and open-circuiting of branches

摘要

The problem of obtaining expressions for symbolic circuit functions is considered A generalization of the formula for separating parameters suggested by V. Foisner is presented for the circuits with different types of controlled sources and ideal operational amplifiers. The derivative circuits are formed from the initial circuit using short-circuiting and open-circuiting of passive components or controlled sources, which enables all the processing to be carried out at the scheme level without forming the circuit equations or its graph. An algorithm is proposed for obtaining expressions of the circuit determinant. The main results are used in a new version of the SYMBOL program for a personal computer.
