摘要

解决了当一个高斯-马尔可夫过程输入到一个sigma-delta调制器时，量化噪声谱的逼近问题。该流程使用状态空间方法建模。精细量化近似用于导出输出谱的表达式。得到了与Gray[1990]分析相似的结果

An approximate analysis of sigma-delta modulation of a Gauss-Markov process

Addresses the problem of approximating the quantization noise spectra when a Gauss-Markov process is input to a sigma-delta modulator. The process is modeled using a state space approach. Fine quantization approximations are used to derive expressions for the output spectrum. Results similar to those of Gray's [1990] analysis are obtained
