An instrumentation amplifier is a closed - loop gain block that has a differential input and an output that is single - ended with respect to a reference teminal . it must amplify the differential input acurately and suppress any unwanted common - mode signals 仪表放大器是一种能精确放大两输入端之间的差模信号而抑制任何共模信号,并将差分输入转换为单端输出的放大器。
Common-mode signal is the component of an analog signal which is present with one sign on all considered conductors. In telecommunication, common-mode signal on a transmission line is known as longitudinal voltage.
common-mode signalとは意味:同相信号{どうそう しんごう} common-mode signal meaning:[Electronics] The algebraic average of two signals applied simultaneously to the two ends of a balanced circuit, such as a differential amplifier. Compare COMMON-MODE INPUT SIGNAL. common-mode signal перевод:1) синфазный сигнал 2) синфазная помеха
