1.	Most biomedical signals of practical interest can be decomposed into a sum of sinusoidal signal components. For the class of periodic signals, such a decomposition is called a _______ series.(a) fourier(b) discontinuous(c) continuous(d) frequencyI had been asked this question during an online exam.Question is from The Main Amplifier and Driver Stage in portion Recording System of Biomedical Instrumentation
Answer» Correct ANSWER is (a) fourier For explanation I would say: It is called a Fourier series. The term SPECTRUM is used when referring to the FREQUENCY content of a signal. The process of OBTAINING the spectrum of a given signal using the basic mathematical tools is known as a frequency or spectral ANALYSIS.
