Abstract
Decoding apparatus for decoding received adaptive differential pulse code modulation data signals which includes unit for quickly detecting errors in the data values in the form of unallocated values or values which are unlikely to occur. The apparatus is intended for use in cordless telephones to eliminate extraneous and disturbing sound signals which can be generated by the decoding apparatus when the signals received by the telephone become weak and are misread before a cyclic redundancy check circuit detects the error.
