PURPOSE:To eliminate the effect due to the erroneous identification, by subtracting the value of the memory element selected by the presumed identification value of the 2nd data and at the same time selecting zero in case the 2nd data is near the signal identifying border line. CONSTITUTION:The error candidate detection output is generated by preidentifying circuit 1 in case the 2nd data is near the signal identifying border line; and otherwise the presumed identification value is delivered respectively. Then zero is selected to the error candidate detection output; and the values of memory elements 30 -33 are selected to the presumed identification value each. After this, the selected value is subtracted from the 1st data in subtractor 20, and then the presumed identification is given to the 1st data through final identifying circuit 21. |
