__________ is not the property of instrumentational amplifier.(a) Extremely high input impedance(b) Very low CMRR(c) Low bias and offset currents(d) High slew rateThis question was posed to me in an interview for job.This interesting question is from Single Channel Telemetry System in section Biomedical Telemetry of Biomedical Instrumentation

Answer»

Correct option is (b) Very low CMRR

To elaborate: Instrumentational amplifiers have very HIGH CMRR. The INSTRUMENTATION amplifier offers the following advantages for its applications in the biomedical field. Some of them are like extremely high input IMPEDANCE, low bias and offset currents, high slew rate.
