A time-sharing analog multiplier

This article describes the design of a high speed electronic analog computing circuit which easily lends itself to time-sharing applications. By making use of a special high accuracy electronic switch and circuitry carefully designed to be independent of tube characteristics, it was possible to achieve a full-scale accuracy of better than 0.2 per cent over a wide range of input values. The unit described was built to carry out 400 complete multiplications and divisions in one second.
