The isolation includes different supply voltage sources and different grounds on each side of the isolation barrier.(a) True(b) FalseThe question was posed to me in an interview.My question is based upon Biomedical Signal Analysis and Processing Techniques in chapter Recording System of Biomedical Instrumentation

Answer»

Correct answer is (a) True

Explanation: The isolation includes different SUPPLY voltage SOURCES and different grounds on each SIDE of the isolation barrier. Three methods are used in the design of isolation amplifiers: (i) transformer isolation (ii) OPTICAL isolation (iii) capacitive isolation. Isolation amplifiers are COMMONLY used for providing protection against leakage currents.
