数字压扩增量调制器设计应注意的问题

Matters to Be Concerned On The Design Of The Digital Compression - Expansion Delta Modulator

本文提出数字压扩增量调制器设计应注意的三个问题,即抽样频率、数字检测长度和最大最小控制电流的压缩比三个参数问题,并对这三个参数进行分析。

This article focuses on the three matters to be concerned on the design of the digital compression - expansion delta modulator. That is, sampling frequency, digital dictation length and the compression ratio of maximum and minimum controlling electric current. The article also makes a further analysis on the determination of the three parameters.
