is quantified, the large input signal uses a large quantization interval, and the small input signal is small quantization interval, so it can be expressed with fewer digits in the case of satisfying the precision requirement. When sound data is restored, the same rules apply. In the nonlinear quantization, two correspondence relations are defined between the amplitude of the sampled input signal and the quantization output data, which is called the M-law-expanding (companding) algorithm and th
