A PCM signal processor for extracting data and error check words from a serial PCM data block contains a serial-to-parallel converter and de-interleaver to present the words in the PCM data block synchronously, circuitry for forming an error pointer and an auxiliary error pointer from the words in the PCM data block error pointer, delay circuitry for forming a data word from the error pointer and the auxiliary error pointer, and error correction and detection circuitry using the data word error pointer. |
