    摘要: In an ADPCM encoding and decoding system comprising an encoder having an adaptive predictor and an adaptive quantizer and a decoder having an adaptive predictor and an inverse adaptive quantizer, the adaptive predictors each comprise: an adaptive-zero predictor of an arbitrary order and an adaptive-pole predictor of an arbitrary order, for input signals with time-varying frequency components; a fixed-pole predictor of an arbitrary order, for input signals the frequency composition of which remains substantially invariant over time; and an offset predictor for rejecting an offset component of the input signals, these elements being connected in series. The adaptive-zero and adaptive-pole predictors generate estimates for voice signals with time-varying frequency components. The fixed-pole predictor generates estimates for voiceband data signals the frequency components of which remain substantially invariant over time. The adaptive predictors effectively operate for voice and voiceband data signals, providing a higher prediction gain. The quantizer provides a stably higher signal-to-quantization noise ratio for modem signals.

    摘要: An adaptive digital filter which is used, for instance, for a prediction filter in an ADPCM modulator and an ADPCM demodulator, for providing stable operation and minimum phase shift response. The filter (FIG. 4, FIG. 5) has three parallel branches (A,B,C), two (A,B) of them have a plurality of series connected non-recursive filter elements (A.sub.1 -A.sub.n, B.sub.1 -B.sub.n) each of which has degree not larger than three relating to an operator (Z.sup.-1), and third branch (C) is merely a conductive line. Tap coefficients (c.sub.1, c.sub.2, . . ., d.sub.1, d.sub.2, . . . ) of non-recursive filter elements change according to solutions of the transfer of the filter. A numerator and/or a denominator of the transfer function of the present filter is a Chebychev polynominal relating to an operator (Z.sup.-1), and has a zero point and/or a pole. The solutions (w.sub.i, v.sub.i) of a numerator and a denominator locate alternately on a unit circle (FIG. 6) on a Z.sup.-1 plane. When solutions of the transfer function do not locate alternately on said unit circle, tap coefficients (c.sub.1, c.sub.2, . . . , d.sub.1, d.sub.2, . . . ) are not updated, since non-alternate solutions do not assure stable operation and/or minimum phase shift response of the filter.

    摘要: An adaptive digital filter which is used, for instance, for a prediction filter in an ADPCM modulator and an ADPCM demodulator, for providing stable operation and minimum phase shift response has been found. The filter (FIG. 4, FIG. 5) has three parallel branches (A,B,C), two (A,B) of them have a plurality of series connected non-recursive filter elements (A.sub.1 -A.sub.n, B.sub.1 -B.sub.n) each of which has degree not larger than three relating to an operator (Z.sup.-1), and third branch (C) is merely a conductive line. Tap coefficients (c.sub.1, c.sub.2, . . . , d.sub.1, d.sub.2, . . . ) of non-recursive filter elements change according to solutions of the transfer function of the filter. A numerator and/or a denominator of the transfer function of the present filter is a Chebychev polynominal relating to an operator (Z.sup.-1), and has a zero point and/or a pole. The solutions (w.sub.i, v.sub.i) of a numerator and a denominator locate alternately on a unit circle (FIG. 6) on a Z.sup.-1 plane. When solutions of the transfer function do not locate alternately on said unit circle, tap coefficients (c.sub.1, c.sub.2, . . . , d.sub.1, d.sub.2, . . . ) are not updated, since non-alternate solutions do not assure stable operation and/or minimum phase shift response of the filter.
