Adaptive prediction differential-PCM transmission method and circuit using filtering by sub-bands and spectral analysis |
摘要 |
Adaptive differential PCM system using both adaptive quantization and adaptive prediction. The adaptive prediction is carried out in adjacent frequency bands on as many signals as are obtained by weighting the quantized signal by coefficients obtained by spectral analysis in the bands of the quantized signal.
