When both signals are the same, a common signal element due to the two inputs can be defined as the average of sum of the two signal

(a)  

When two separate inputs are applied to the op- amp, the resulting difference signal is the difference between two inputs

(a)  

Since any signal applied to an op- amp in general have both in-phase and out-of-phase components, the resulting output can be expressed as:

(a)  

type of op amp operations

(a)  

type of op amp operation

(a)  

type of op amp operation

(a)  

type of op amp operation

(a)  

The higher the CMRR, the (a)   and a high CMRR means that the amplifier is amplifying the desired signals and discriminating against the common-mode signa

contains a number of differential amplifier stages to achieve a very high voltage gain

(a)  

It is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs
