摘要

Under the criterion of minimizing entropy of the linear prediction residual of the input signal used in calculating a series of inputted PARCOR coefficients, PARCOR coefficients with greater absolute values are quantized with higher quantization precision in order to suppress increases in the encoding size of said linear prediction residual, which result from PARCOR coefficient quantization error. When expressing a PARCOR coefficient as a value with a prescribed number of bits, a value expressing the PARCOR coefficient is outputted that has a greater number of significant bits from the highest order bit toward the lowest order bit, the greater the absolute value of the inputted PARCOR coefficient is.
