ABSTRACT:
A pulse code modulation signal processor extracts signal processor control words from a serial pulse code modulation data stream also containing error detection and correction codes. The PCM signal processor includes a serial-to-parallel converter to convert the serial PCM data stream into the signal processor control words in a parallel format, an error detector connected to the serial-to-parallel converter for forming an error signal indicating the presence or absence of an error in the control words, registers for storing first signal processor control words when the error signal indicates the absence of an error in the signal processor control words and for preventing the storage of the signal processor control words when the error signal indicates the presence of an error in the signal processor control words, and a transient error correction circuit for storing second signal processor control words when the error signal first indicates the presence of an error and subsequently indicates the absence of an error and when the second control signals of two successive PCM data streams are equivalent.
