MULTIFUNCTIONAL FAST-ACTING FERRITE DIODE ELEMENTS,

摘要

Several schemes of multifunctional logic elements are examined;they are based on the well-known principle of switching the advancing currents by turning off the diodes by output voltages of ferrite cores. With any combination of binary information,three cores switch their magnetism. Any logic operation is performed in one cycle. The results of several logic functions can be taken off simultaneously. The same switching principle was used for designing a three-point universal logic element (block diagram given). Three cores out of six switch when any information arrives. Such an element is essentially a single-digit summer with three inputs;the element can also be regarded as an 8-position decoder designed with three pairs of cores. A simple-circuit multifunctional element is able to perform all logic functions except for the EQUIVALENCE OPERATION AND ITS NEGATION. The above elements were tried with 0.25VT 2times 1.4times 1mm cores and tested at 500kHz with advancing currents of about 0.5amp. (Author)
