Question

What should be the frequency response of the amplifiers that are used for the amplification purpose of the input signal in medical devices?

(a) high frequency response

(b) low frequency response

(c) frequency response has no role to play in it

(d) average frequency response

This question was addressed to me during an internship interview.

I need to ask this question from Biotelemetry topic in section Biomedical Telemetry of Biomedical Instrumentation

Answer 1

Correct option is (b) low frequency response

To explain: The response should be down to less than one hertz which is a very frequent requirement. The bioelectric signals in medical science contain components of extremely low frequency. Thus the amplifiers must also have a low frequency response.
