摘要
A device and method for counting bit errors in the received signal in digital communication, and a device and method for judging whether received signal is aural signal or control signal and for outputting identification signal, the number of errors, and decoded signal. Generally in bit error counters, there is a problem that an exact error rate cannot be calculated if an error that is incorrectable is included in a decoded signal. To overcome the problem, a status monitoring unit (22) is provided, which outputs a predetermined error rate utilizing information in the decoding process if an error is included in the decoded signal. Further, an error detection unit (28) is provided, which outputs a predetermined error rate if an error is included in the decoded signal. In identification devices, there is a problem that signal cannot be identified if an error that is undetectable is included, because the kind of the input signal is identified based on the result of error detection. To solve this problem, a signal identification unit (1206) is provided, which identifies the input signal based on the error detection result, the decoding result, and the number or errors. IMAGE
