1.	Most biomedical signals of practical interest can be decomposed into a sum of sinusoidal signal components. For the class of finite energy signals, the decomposition is called the ____________(a) Fourier series(b) Fourier transform(c) Laplace transform(d) Laplace seriesThis question was posed to me in semester exam.The question is from The Main Amplifier and Driver Stage in division Recording System of Biomedical Instrumentation
Answer» The correct answer is (b) Fourier transform Best explanation: For the class of finite energy signals, the decomposition is called the Fourier transform.For the class of periodic signals, such decomposition is called a Fourier series. The PROCESS of obtaining the spectrum of a given signal USING the basic MATHEMATICAL tools is known as a frequency or spectral ANALYSIS.
