| 摘要 | PURPOSE:To improve the probability of correction of an actual information section even if an error occurs to an additional bit section by deciding on the specific pattern of the head part of a code and then calculating parity. CONSTITUTION:It is known that the starting six bits of data at the head part of the code are 0, so a parity AND gate control circuit 9 closes AND circuits 10 and 11. A control circuit 9 counts the number of send data and opens the AND gates 10 and 11 when read data arrives at the AND gates. Therefore, an error occurring to the head part of the code never causes a failure in correcting other parts and a failure in correcting the actual error occurrence position resulting from that the six bits which are 0 are judged as 1. | ||||||
