共模抑制比（信息科学术语）
为了说明[[差分放大电路]]抑制[[共模信号]]及放大差模信号的能力，常用共模抑制比作为一项[[技术指标]]来衡量，其定义为放大器对差模信号的[[电压放大倍数]]Aud与对共模信号的电压放大倍数Auc之比，称为共模抑制比，英文全称是Common Mode Rejection Ratio，因此一般用简写CMRR来表示，符号为Kcmr，单位是分贝db。

*中文名:[[共模抑制比]]

*外文名:common mode rejection ratio

*应用学科:模拟电子电力

*领    域:[[信息科学]]

*英文简称:CMRR

*定    义:放大电路对[[差模信号]]的电压增益与对[[共模信号]]的电压增益之比绝对值
