Abstract:

The Circuit Analysis Program was prepared for the IBM 704 computer and is written in the FORTRAN and SAP-FORTRAN languages. In this report, the program is used to analyze R-L-C resistance, inductance, and capacitance electric networks and, once the proper analogies are made, resolve problems relative to obtaining eigenvalues and roots of polynomials and solving systems of general linear equations. Examples of some of the above problems are provided. The total number of equations for each problem cannot exceed 30. Accuracy of the solution is improved by using two 36 binary bit words to represent each number, but execution time is sacrificed. The requestor controls the format used to read the equation parameters thereby, the flexibility of the program is increased, and the possibility of transcribing errors is reduced. Three methods for evaluating a determinant with quadratic elements were tried, and it was decided that the method of false position is the most effective because of its advantageous storage and time requirements and greater accuracy.
