Data recognition apparatus includes a temporary storage to hold three data bits, a readable storage to store eight different sequences which are expected to occur, and a comparison means to find the closest match of the contents of the temporary storage with the readable storage at each bit time. Error detection and error correction are realized as each bit is recognized three times sequentially. The apparatus may use surface acoustic wave and charge coupled device filter banks, and analog to digital conversion plus data processor comparison.
