Multihole Ferrite Core Configurations and Applications

Combined gating and memory functions may be performed by the use of multihole ferrite cores called transfluxors. By proper topological design, transfluxors may be made noncritical to control pulse amplitude. In addition, by use of novel compensation and ac driving techniques, the transfluxor may be operated noncritically over an ambient temperature range from -50°C to +200°C. By making full use of multiple path geometries single multihole disks referred to as logicors have been designed to perform such complex logical operations as sequential pulse gating, odd parity checking, binary half adding, selective channeling, etc. One such logicor may replace as many as twelve switching devices in a logical circuit.
