Abstract
Electronic differential analyzers, or simulators, employ computing elements which must be physically realizable electric circuits, and this fact introduces unavoidable errors into the differential-equation solutions. These errors are investigated mathematically for the general case of differential equations with constant coefficients. It is found that in certain cases an error of 1 per cent can be introduced by an adder bandwidth 2,000 times the highest frequency in the differential-equation solution.Keywords
