We use the DFT to compute the amplitude spectrum of a sampled data sequence with a sampling rate fs = 2; 000 Hz. It requires the frequency resolution to be less than 0.5 Hz. Determine the number of data points used by the FFT algorithm and actual frequency resolution in Hz, assuming that the data samples are available for selecting the number of data points.
