1.	To achieve the ______________ required for medical applications, the amplifier must have large values of coupling capacitance.(a) random frequency response(b) high frequency response(c) average frequency response(d) low frequency responseI had been asked this question in an interview.Enquiry is from Biotelemetry topic in section Biomedical Telemetry of Biomedical Instrumentation
Answer» Correct OPTION is (d) low frequency response For explanation: In all RC-coupled amplifiers, low frequency response is limited by the reluctance of the COUPLING capacitors. The response should be down to less than ONE HERTZ which is a very frequent REQUIREMENT. To achieve the low frequency response required for medical applications, the amplifier must have large values of coupling capacitance.
