Title: Improvements in or relating to magnetic core matrix decoders
IPC: H03M7/00
Filed: 1961-02-20
Abstract: 917,234. Electric selective signalling systems. BURROUGHS CORPORATION. Feb. 20, 1961 [March 7, 1960], No. 6089/61. Class 40 (1). [Also in Group XXXIX] A magnetic core recoding matrix, Fig. 1, is characterized in that each core 10, 12, 14 carries a plurality of output windings, all the output windings being arranged in a number of groups each group comprising one winding from each core. In operation, pulses representing input binary data (100 as shown) are applied to input windings 16, 18 and 20. On the second half of each pulse each core will change its state, the direction of change corresponding to the binary input data, and this will cause a pattern of output voltages to occur in the output winding. The output windings are so connected in groups of three that in only one group is there a resultant output of +3 units (other groups having +2, +1, -1, -2 or - 3 units), and this group is recognized by applying a bias of - 2 units from a source E whereby only one diode conducts. Thus a combination of three input markings causes one of eight output leads e 0  to e 7  to be marked. In a second embodiment (Fig. 2, not shown) the diodes are replaced by transistors.
