A COMPUTER PROGRAM FOR THE FREQUENCY ANALYSIS OF LINEAR ELECTRICAL NETWORKS.
SYLVANIA ELECTRONIC SYSTEMS-WEST MOUNTAIN VIEW CA ELECTRONIC DEFENSE LABS
A computer program for performing frequency analysis of linear electrical networks with up to 40 nodes is described. The network is described to the program by a list of the types of elements, their node connections and their values. The frequency functions to be calculated are defined by choosing from a prepared set of equations and listing the variables to be used in these equations. Subroutines are used to describe the frequency functions and transistor models these subroutines may be easily changed to describe models or functions not presently provided. The desired frequency functions are computed in the program by generating the admittance matrix and partially inverting it to obtain the voltages needed in the specified equations. Author
