Question

The process of obtaining the spectrum of a given signal using the basic mathematical tools is known as _______________

(a) time domain analysis

(b) mathematical analysis

(c) spectral analysis

(d) pseudo analysis

This question was addressed to me by my college professor while I was bunking the class.

This interesting question is from The Main Amplifier and Driver Stage topic in chapter Recording System of Biomedical Instrumentation

Answer 1

Correct answer is (c) spectral analysis

For explanation I would say: The process of obtaining the spectrum of a given signal using the basic mathematical tools is known as frequency or spectral analysis. The term spectrum is used when referring to the frequency content of a signal. Most biomedical signals of practical interest can be decomposed into a sum of sinusoidal signal components.
