Abstract
The electronic analog computer, although very useful in solving many problems, and particularly useful in solving dynamic problems described by differential equations, suffers from limitations of accuracy and dynamic range. The digital differential analyzer, although capable of providing any required degree of accuracy or dynamic range, is slow in operation and subject to possible instability of solution due to quantization and the use of finite difference calculus in integration. By combining analog and digital techniques, it is possible to combine the analog advantages of high speed and continuous representation of variables with the digital capability of high precision and large dynamic range.This publication has 0 references indexed in Scilit:
