noun
common mode rejection
Technical term in electronics and signal processing; refers to the ability of a differential amplifier or circuit to reject signals that are common to both inputs.
差動増幅回路の同相分除去比は重要な性能指標です。
The common-mode rejection ratio of a differential amplifier circuit is an important performance indicator.
同相分除去比 (CMRR) is the ratio that quantifies common-mode rejection, while 同相分除去 refers to the rejection itself.
Compound of 同相 (common mode) + 分 (component) + 除去 (removal/rejection). A technical calque from English 'common mode rejection'.
