1.	The ability of the amplifier to reject common voltages on its two input leads is known as ________(a) common mode rejection rate(b) coupled mode rejection rate(c) common mode rejection ratio(d) coupled mode rejection ratioI have been asked this question at a job interview.Origin of the question is Sources of Noise in Low Level Measurements in division Recording System of Biomedical Instrumentation
Answer» Correct ANSWER is (c) common mode REJECTION ratio To explain: 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. It is abbreviated as CMRR (Common-mode rejection ratio).
