The common-mode rejection ratio of a differential amplifier
(or other device) measures the tendency of the device to
reject input signals common to both input. A high CMRR is
important in applications where the signal of interest is
represented by a small voltage fluctuation superimposed on a
voltage offset, or when relevant information is contained in
the voltage difference between two signals. (example-audio
transmission over balanced lines.)
The CMRR is a very important specification, as it indicates
how much of the common-mode signal will appear in your
measurement. The value of the CMRR often depends on signal
frequency.
CMRR is often important in reducing noise on transmission
lines.The CMRR of the measurement instrument determines the
attenuation applied to the offset or noise.
Mathematically,
"It is the ratio b/w diffferitial gain to common mode gain"

Define virtual ground in the op amp?
Alok and Bhanu play the following min-max game. Given the expression N = 9 + X + Y - Z Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be 27 0.0 20 18
