ONE METHOD OF USING TOROIDAL CORES MADE OF FERROMAGNETIC MATERIALS TO CONVERT CONTINUOUS INTO DISCRETE VALUES
FOREIGN TECHNOLOGY DIV WRIGHT-PATTERSON AFB OHIO
The possibility of the operation of ferromagnetic toroidal cores as elements converting a varying continuous current value into discrete form is discussed. The testing of the pulse characteristics of 3 types of cores showed K-222 cores possess the best properties. Two structural circuits for converters using parallel and series data output are suggested. To demonstrate the practical convenience of cores made of ferromagnetic materials as converter elements an experimental unit with parallel output of the output data was assembled. This unit recorded 33 values of a continuous current varying with a frequency up to 1 cps and ranging from 0 to 1 amp in the form of a binary code. The structural circuits considered were relatively simple and were based on ferromagnetic materials which did not possess high-grade pulse characteristics. Use of materials with better characteristics textured ferromagnetic alloys in the form of thin ribbon and the production of new structural circuits may produce effective continuous discrete value.
