Performance of the core-equivalent of the transfluxor shift register

AN ALL-MAGNETIC shift register and logic scheme, using 2- or 3-holed ferrite transfluxors and resistive coupling windings in its operation, has been extensively described in past literature.^1,2 Employment of multiapertured magnetic cores in such circuits has appreciable appeal from a fabrication standpoint over equivalent circuits utilizing toroidal cores and additional coupling windings. The latter, however, are advantageous in the initial development of a logic scheme since adjustments in geometry and relative proportions of elements can be made, either by changing windings and grinding, or selecting cores from stock.
