Abstract:

High-frequency magnetic film parametrons have been made and observed to exhibit two- or three-state operation for a single bias condition. As a two-stable-state device, the magnetic film parametron can be used as a majority decision element in much the same way as the ferrite core parametron. Another useful logical two-state device is a threshold element, in which the input excitation must reach a minimum level to sustain oscillations. The magnetic film inductor, when suitably clocked, can be used as a gate to permit unilateral flow of information in a system. The gating action, controlled by the bias field, can result from the rectified output of a parametron. Proposed logical designs for a two-element binary adder, a binary shift counter, and a shift register are presented. The possibilities of three-state operation are also explored in the logical design of a seven-element ternary full adder.
