ABSTRACT:
An error correction system including a syndrome modifier for receiving a syndrome and operating the equation ##EQU1## where i is an integer greater than or equal to zero, for transforming the syndrome into a new syndrome; an n-1 error correction circuit for receiving the syndromes modified by the syndrome modifier for n-1 error correction, a counter for varying the K value if the n-1 error correction fails; a circuit for outputting an .alpha..sup.K value corresponding to the K output signal of the counter, to the syndrome modifier, an error value operation circuit for receiving the output signal of the n-1 error correction circuit to calculate a substantial error value according to the equation
