ABSTRACT:
An error ratio detector according to the present invention, which detects the error ratio of error correction-coded data with a syndrome, reduces the error pulse occurrence probability by using only the errors in an M (<N) period within each block (of N bits) as errors for calculating the error ratio, and thereby makes it possible to assess the bit error ratio in a high BER region even where blocks are rather long.
