common mode rejection ratio(cmrr) meaning in English
共模抑制比
Examples
- By designing the circuit structure of preamplifier and selecting new elements such as ultra low noise operational amplifier and linear opto - coupler , some difficulties in eeg acquisition is overcome and the common mode rejection ratio ( cmrr ) of preamplifier is highly increased . so eeg can be amplified and detected well
通过对前置放大器等电路结构的精心设计,选用超低噪声的集成运算放大器以及线性光耦合器等新器件,克服了脑电信号采集中经常遇到的一些困难,使前置放大器具有较高的共模抑制比,从而能够较好地放大检测出所需的脑电信号。
