IMPULSE NOISE SUPPRESSION DEVICE

摘要

Digital audio data with error detection bits added thereto is input into an error detection and correction unit 4. The correction unit 4 corrects an error when the error is detected in the digital audio data. The digital audio data output from the error detection and correction unit 4 is input into an impulse noise suppression circuit 6. The suppression circuit 6 is operated for a predetermined time when the error detection and correction unit 4 has detected an error.
