A METHOD OF INCREASING THE ACCURACY AND SPEED OF A DIGITAL INTEGRATOR

Abstract

The possible ways of increasing the accuracy and speed of digital differential analyzers are examined. It is concluded that a conversion to multiple digit increments is expedient. The application of various numerical integration equations when operating with multiple digit increments is considered. The investigation was carried out in solving a second order differential equation based on a comparison of equations for rectangles, trapezoids and average rectangles. It is shown that the speed of a digital differential analyzer can be 10-100 times greater than the speed of the parallel-series type machine. The block diagram is given of a computer which can be used to obtain the algorithm described.
