摘要

结果表明，没有反馈的量化系统对特定频谱型抖动信号的响应与有反馈路径的量化系统有很大的不同。对于每种类型的系统，给出了保证量化误差是广义平稳的条件，没有输入依赖，并且具有可预测的功率谱密度函数。

Dithered quantizers with and without feedback

It is shown that quantizing systems without feedback respond to the use of particular spectrally-shaped dither signals quite differently from those with feedback paths. For each type of system, conditions are given which ensure that the quantization error will be wide-sense stationary with no input dependence and with a predictable power spectral density function.<>
