Multi-Aperture Core Device

The core device requires but a single winding through each aperture and may be operated either as a biased flux coincident current device or as an anti- coincident current device.

For anti-coincident current operation the Y winding is energized at all times when switching of the core is not desired and counteracts either a read or a write current in winding X. With Y de-energized at the time of a write pulse in X, switching of the core may be inhibited by a current in the Z winding. The sense winding detects switching of the core.

For coincident current operation, a bias winding threads two apertures while the X and Y windings thread one aperture each. Coincident currents in X and Y overcome the bias and switch the core. A fifth aperture is threaded by a sense winding. A sixth aperture may be provided for an inhibit winding.
