Magnetic Core Matrix Switch Adder

Abstract

The principle of operation of the three input-two output matrix adders is based upon the saturable transformer characteristics of the magnetic cores. The control and driving windings are matrix connected. This presents a selection scheme which produces an almost instantaneous addition or subtraction of two binary numbers. The carry propagate time is about 0.07 μsec per digit for a pulse length of 0.5 μsec at a PRF of 1 mc.
