1,026,171. Apparatus for comparing the magnitude of two binary numbers. EUROPEAN ATOMIC ENERGY COMMUNITY, EURATOM. Nov. 29, 1963 [Oct. 1, 1962], No. 37160/62. Heading G4M. Apparatus for comparing the magnitude of two binary numbers comprises an electrical means including electromagnetic inductive devices 21, 23 whose impedances to an auxiliary sawtooth current from 1 are varied by simultaneous feeding of electric signals representing digits ai, bi. If the digits ai, bi are equal ferrite cores 21 are saturated and conductive whereas if they are unequal ferrite cores 23 are saturated and conductive and, according to the polarity of this current, one of diodes D1K, D2K conducts a signal to one of outputs A > B, A < B. Successive similar circuits test the equality of each of the digits in decreasing order of significance. Preferably the working points of cores 21 is at twice the saturation field strength whereas that of the cores 23 is at saturation field strength. The hysteresis loop for the cores 21 has an amplitude equal to the saturation field strength whilst that of cores 23 has twice this amplitude. |
