1. Note that the " data scrubbing " operation activates a parity check . 2. They had a 24-bit word, of which one bit was for parity check . 3. The rows of a parity check matrix are the coefficients of the parity check equations. 4. The rows of a parity check matrix are the coefficients of the parity check equations. 5. Another possibility would be a concatenation of a Hamming code with a low density parity check code. 6. The reverse side of the medal depicts a Hamming parity check matrix for a Hamming error-correcting code. 7. For example, the parity check matrix 8. The limit on the number of bits set is similar to, but strictly stronger than, a parity check . 9. 1AESS used stores ( memory units ) with 26 bit words, of which two were for parity check . 10. He also invented the procedure for automatic error detection known as parity check , which is used in almost all computers today.
