Using multiaperture Ferrites for logic functions

A multiaperture ferrite structure, developed by New-hall and others for use in shift registers, forms a basis for performing logical operations through the use of multiple input windings. The binary signals are bipolar (pulses of similar shape but opposite polarity) rather than unipolar, and logical functions may be realized using only connecting wire and a sufficient number of properly clocked apertures. Linearly separable Boolean functions of two variables are realizable on a single aperture, and a single aperture may also be operated as a threshold logical element. Experimental results indicating the feasibility of such operation are also reported.
