Abstract : Following some introductory remarks on the application of analogue computation, the most habitual purely electrical methods to form products and quotients are summarized. Contrary to multiplication there are very few methods for division which are strongly limited with respect to their speed of operation and accuracy, and the transformation of a division into a multiplication always leads to a loss in the speed of operation or to a loss in accuracy. Two simple methods are therefore described for the rapid formation of quotients, of which one is specially indicated for d.c. voltages while the second method is preferably suited to form the ratio of two a.c. voltages. Both methods allow simultaneous multiplication. By means of two practical examples it is shown that it is possible to realize both methods as particular simple and reliable passive units. The indicated circuits allowed an accuracy of better than 1% up to frequencies of more than 200 kcps. On principle, it is possible to realize higher speeds of operation as well as better accuracies.
