BURST ERROR DETECTION METHOD

摘要

PURPOSE:To supervise the quality of line by measuring the length of a burst error and the length of an error free section base on an error detection signal obtained by error correction. CONSTITUTION:An input terminal 1 is connected to the input of a code section 2 and an output of the code part 2 is connected to a communication line 4 by a transmission terminal 3. A reception terminal 5 of the communication line 4 is connected to the input of a decoding part 6, a data output signal 7 from the decoding part 6 is fed to an output terminal 6 and an error detection signal 9 is fed to the input of a burst length measuring part 10. The burst length measuring part 10 measures the length of a burst error and the length of an error free section based on an error detection signal 9 of the decoding part 6 and gives output to a burst length output terminal 11 and an error free length output terminal 12.
