Posted under Cognitive Radio

Answer: (b).Cepstrum coefficients are obtained by taking Fourier transform of decibel spectrum Explanation:Cepstrum coefficients are features employed in speech signal processing. It is obtained from the spectrum of a speech signal. Cepstrum coefficients are obtained by taking the Laplace transform of the decibel spectrum. Shifted delta cepstrum coefficients measure the changes in the speech spectrum over multiple frames of spectrum to model language characteristics.
