CMRR is measured in ___________(a) v/s(b) dB(c) dB/s(d) dB/msThe question was asked at a job interview.The above asked question is from Biomedical Signal Analysis and Processing Techniques in division Recording System of Biomedical Instrumentation

Answer»

Correct answer is (b) dB

Explanation: CMRR is an important specification REFERRED to the differential amplifier and is NORMALLY expressed as decibels. The ability of the amplifier to reject common voltages on its TWO input leads is known as common-mode rejection. It is specified as the ratio of common-mode input to differential input to elicit the same RESPONSE.
