Economical Circuits for the Analog Solution of Algebraic Equations

The only methods previously available for the design of stable analog circuits for the solution of algebraic equations involved extensive preparatory calculations or the use of an excessive number of amplifiers. This paper examines the causes of instability and gives a method which enables a stable circuit using the minimum of equipment to be designed for any nonsingular set of algebraic equations. The method is ideal for the design of high-speed circuits.
