ABSTRACT:
A pulse code modulation signal processor extracts data words from a serial data stream. The signal processor includes a serial-to-parallel converter to convert the data stream into parallel data words, a de-interleave circuit to add different delays, and thus synchronize with each other, the extracted data words, a circuit for forming an error pointer from the data words, an error pointer comprising data word error pointers each indicating the presence of an error in a different data word, an error pointer shift register for synchronizing the error pointer with the data words from the de-interleave means, and an error detector and corrector.
