Rate buffer control of predicted signal decimation and interpolation for adaptive differential pulse code modulator

摘要: A predictive coding signal communication arrangement includes, at the transmitter, a subtractor for subtracting delayed predicted signals from current input to produce difference signals. Predicted are generated by adding signals, and delay of produces The also applied coder Huffman coding, run-length or like, then rate buffer reducing data variability. In order prevent overflow buffer, control is which represents level filled. used reduction decimation disparity, corrected similar signal, an inverse interpolation increase signal. Anti-alias ghost filters controlled switched after period time.
