КОСС
Для операционных усилителей (ОУ) коэффициент ослабления (подавления) синфазного сигнала - это очень важная величина, а для усилителя мощности важно, что низкое значение CMRR служит дополнительным источником интермодуляционных искажений усилителя. Эта величина представляет собой коэффициент усиления ОУ для синфазного напряжения, выраженный в децибеллах.

common mode rejection ratio
CMRR (abbreviation)
ratio of the voltage applied between a specified reference point and the input terminals, when connected together by a specified circuit, to the voltage required between the input terminals to produce the same value of the output
NOTE 1 – The common mode rejection ratio is usually expressed in decibels and can depend on the frequency, the waveform and the method of measurement.
NOTE 2 – Common mode rejection ratio can also apply to quantities other than voltage.

rapport de réjection de mode commun
rapport de la tension appliquée entre un point de référence spécifié et les deux bornes d'entrée connectées l'une à l'autre par un circuit spécifié, à la tension nécessaire entre les bornes d'entrée pour produire la même valeur de sortie
NOTE 1 – Le facteur de réjection de mode commun est généralement exprimé en décibels et peut dépendre de la fréquence, de la forme d’onde et de la méthode de mesure.
NOTE 2 – Le rapport de réjection de mode commun peut aussi s'appliquer à des grandeurs autres que les tensions.
