Abstract
A circuit for monitoring digital data in the form of words comprising a plurality of digits comprises a shift register through which the digital data is fed and one or more memory devices arranged to compare the data in the shift register with predetermined data stored in the memory device or devices. The memory device or devices produce a numerical count of the number of digits either which are correct or which are incorrect and that number is compared by a comparison circuit with a reference value in order to control dumping or further processing of the data.
