ERROR RATE DETECTING CIRCUIT AND RECEPTION TERMINAL EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To detect and measure the bit error of a transmission error caused by a transmission line during the operation of digital broadcasting and digital data transmission. SOLUTION: This equipment is provided with an error correcting circuit 1 for performing the error correction of a digital stream signal, corrected bit number detecting and holding circuit 2 for detecting and holding the number of corrected bits, reference bit number table circuit 3 for holding the reference number of bits to be calculated at every unit time, division circuit 4 for dividing the number of corrected bits with the reference number of bits, and output circuit 5 for outputting the divided result of the division circuit 4.
