1.	In medical devices, the amplifiers that are used for the amplification purpose of the input signal must have ___________(a) low frequency response(b) high frequency response(c) average frequency response(d) frequency response has no role to play in itThe question was posed to me in final exam.My question is based upon Smart Sensors in portion Physiological Transducers of Biomedical Instrumentation
Answer» Right answer is (a) low frequency response For explanation: The BIOELECTRIC signals in medical science CONTAINS components of EXTREMELY low frequency. THUS the amplifiers must also have a low frequency response. The response should be down to less than ONE hertz which is a very frequent requirement.
