Answer 1

1. The primary purpose of using a Fourier series is to represent any periodic signal as a sum of simpler sinusoidal components. Therefore, the correct answer is b) To represent any periodic signal as a sum of simpler sinusoidal components. 2. All the options listed are applications of the Fourier series. Therefore, the correct answer is e) None. 3. The Fourier Transform is applicable to both periodic and aperiodic signals. Therefore, the correct answer is c) Both periodic and aperiodic signals. 4. The property that differentiates the Fourier Transform (FT) from the Fourier Series (FS) is that FT is used for both periodic and aperiodic signals, while FS is for periodic signals. Therefore, the correct answer is c) FT is used for both periodic and aperiodic signals, while FS is for periodic signals. 5. One primary use of the Laplace Transform is converting differential equations into algebraic equations. Therefore, the correct answer is b) Converting differential equations into algebraic equations. 6. All the options listed are methods used to compute the Inverse Laplace Transform. Therefore, the correct answer is e) None. 7. The 2-Transform is specifically used for continuous-time signals. Therefore, the correct answer is a) Continuous-time signals.
