证明了定点采样值的分段量化处理的可行性,发现了一种具有特殊性质的模拟余量A2。A2可正确运用于模拟信号被连续采样和量化的多种应用领域,例如:模数转换器、亚采样和图像压缩编码,从而导致更好的结果和讨论。 This paper proves the feasibility of the segmentation quantization of fixed-point samples and finds a kind of analog margin A2 with special properties. A2 works well in a variety of applications where analog signals are continuously sampled and quantized, such as analog-to-digital converters, sub-sampling, and image compression coding, resulting in better results and discussion.
