Self-correcting coding circuit, and circuit arrangement for decoding binary information

Claim 1

A SELF-CORRECTING CIRCUIT ARRANGEMENT FOR CODING INFORMATION IN ANY SUITABLE BINARY CODE, SAID ARRANGEMENT COMPRISING A TEST MATRIX WITH COUPLING ELEMENTS ARRANGED AT PREDETERMINED CROSS-POINTS THEREIN, THE RELATIVE VALUES OF SAID COUPLING ELEMENTS BEING DETERMINED AS FUNCTIONS OF THE BINARY CODE TO BE PRODUCED; MEANS FOR SUPPLYING TO THE INPUT OF SAID TEST MATRIX THE INFORMATION TO BE ENCODED; A SIGNIFICATION MATRIX WITH COUPLING ELEMENTS ARRANGED AT PREDETERMINED CROSS-POINTS THEREIN, SAID ELEMENTS HAVING VALUES TO PRODUCE THE DESIRED BINARY CODE, SAID SIGNIFICATION MATRIX BEING COUPLED TO THE OUTPUT OF SAID TEST MATRIX AND INCLUDING 2N INPUT COLUMNS AND N DOUBLE OUTPUT ROWS, WHEREIN "N" IS EQUAL TO THE NUMBER OF VARIABLES; OUTPUT MEANS COUPLED TO THE OUTPUT OF SAID SIGNIFICATION MATRIX FOR SELECTING WHICH OUTPUT LEADS OF SAID OUTPUT MEANS ARE TO BE MARKED IN ACCORDANCE WITH THE DESIRED CODE; SAID TEST MATRIX INCLUDING 2N ROWS AND COLUMNS AND HAVING RELATIVE VALUES OF COUPLING ELEMENTS DETERMINED BY MULTIPLYING IN MATRIX FORM THE BINARY CODE TO BE PRODUCED BY THE RESPECTIVE TRANSPONENT THEREOF SO AS TO ALTER THE NORMAL INPUT TO THE SIGNIFICATION MATRIX TO PRECLUDE AN IMPROPER MARKING AS A RESULT OF A COLUMN FAILURE.
