[′käm·ən ‚mōd ri′jek·shən ′rā·shō]
(electronics)
The ratio of the gain of an amplifier for difference signals between the input terminals, to the gain for the average or common-mode signal component. Abbreviated CMRR.

Currently there is no measurement system on the market with IsoVu's combination of high bandwidth, 2000V common mode voltage range and breakthrough common mode rejection ratio.
This series offers powerful filtering protection from electromagnetic interference (EMI), provides differential to common mode rejection performance and helps overcome the bandwidth limitations common to Category 5 twisted pair cabling.
These tests were conducted over several sample rates and included: noise and offset, impulse response amplitude and phase accuracy, full scale harmonic distortion, signal level distortion, common mode rejection and gain accuracy.
5 [mu]V/[degrees]C, a high power supply rejection and common mode rejection ratio of 100 dB min.
The device also features a fast switching speed, up to 15Mbit/sec, and uses Fairchild's proprietary Optoplanar[R] packaging technology and optimized IC design to achieve high common mode rejection (CMR) of 20kV/os minimum, allowing the device to operate in noisy industrial environments.
Superior common mode rejection of up to 30kV/s is achievable, while continuing to communicate through the event.
