Polynomial Root Determination by an Equivalent Transfer Function Simulation on an Iterative Analog Computer

The methods for determining the roots of polynomials by analog computer techniques are varied, but stability analysis is usually of chief concern. The computer approach used in this paper always produces stable operation, and introduces an equivalent transfer function representation of the polynomial, a linear transformation, and a generalized iterative analog computer program. The accuracy obtainable is not comparable to that of digital programs; however, the procedure is basic to engineering analysis and should not be overlooked from the academic viewpoint.
