What is the purpose of using a "Gaussian window" in spectral analysis?

A) To amplify specific frequencies

B) To reduce spectral leakage

C) To create sharp cutoffs in frequency response

D) To simplify the computations

Answer: B) To reduce spectral leakage

Explanation: The Gaussian window is used in spectral analysis to reduce spectral leakage by smoothly tapering the signal, which helps in obtaining a clearer frequency representation.
