Explain about Common-Mode Rejection Ration.



- CMRR is used for measuring the tendency of the device that is to reject the input signals.

- These signals can be from both input leads.

- CMRR at a high level is important, as the signals of interest are represented by a small set of fluctuations of voltage.

- The voltage fluctuations are superimposed on, possibly a large voltage offset.

- Superimposition of the signals might also be done, when the information of relevance is contained in the voltage difference between the two signals.

  • CMRR it is the ratio of the power of the differential gain to the common mode gain...
    and is used for measuring the tendency of the device that is to reject the i/p signals.it should be as high as possible.

  • correct your answer..as it is ''unwanted input signals '' not the ''input signal ''..in your first line of you answer.
