Apparatus for data entry and error detection of digital information. Data clocked into a register undergoes a correlation comparison against a data word already stored within the comparator circuit and a convolution check in which the bits of the data word are compared with each other in a predetermined order. If the input data satisfies these tests, the data word is placed in memory where it may be acted upon by other devices. Patent
