Optical rejection ratio
WebIn electronics, the common mode rejection ratio(CMRR) of a differential amplifier(or other device) is a metric used to quantify the ability of the device to reject common-mode signals,i.e. those that appear simultaneously and in-phaseon both inputs. An idealdifferential amplifier would have infinite CMRR, however this is not achievable in practice. WebThe ability of a receiver to reject interfering signals at the image frequency is measured by the image rejection ratio. This is the ratio (in decibels) of the output of the receiver from a signal at the received frequency, to its …
