Abstract:

By programming pairs of amplifiers to represent the real and imaginary parts of complex variables on an analog computer, techniques are developed which 1 permit the mechanization of the method of steepest descents, for finding roots of complex functions, in Cartesian coordinates 2 simplify the generation of square-root and division circuits 3 allow the generation of complex functions utilizing the Cauchy integral theorem and 4 enable a programmer to scan the z-plane efficiently when electronic mode control and track-andhold circuitry are available. The report is documented with examples which show that these techniques frequently provide more efficient programs, in terms of equipment, than current methods. Author
