Given the sinusoid
obtained using a sampling rate of fs = 8; 000 Hz, we apply the DFT to compute the amplitude spectrum.
a. Determine the frequency resolution when the data length is 100 samples. Without using the window function, is there any spectral leakage in the computed spectrum? Explain
b. Determine the frequency resolution when the data length is 73 samples. Without using the window function, is there any spectral leakage in the computed spectrum? Explain.
