Abstract
A system efficiently determines and stores in memory the logical bit positions of bits in which bit errors have occurred in digital recording devices, etc. The system measures bit errors by comparing a test bit string with a correct bit string, and includes a bit string memory that stores the correct bit string, a word comparator for comparing corresponding words from the test bit string and the correct bit string, an error word content memory that stores the contents of the words containing errors, and an error word position information memory that shows the positions in the correct bit string which correspond to error words in the test bit string that contain the errors. Bit error information in a desired visual format is obtained by performing calculation processing on these memory values.
