Assume that acoustic pressure has been recorded for a duration of 1s. The total number of samples is 1,024. FFT is applied to determine the frequency spectrum of the signal. a) Calculate 1) The sampling frequency 2) The Nyquist frequency 3) The frequency resolution of the FFT spectrum b) If the signal is a pure tone (harmonic signal) of frequency 33.7 Hz, what sorts of problem do you expect to observe in the FFT spectrum calculated based on the recorded data? What could be done to mitigate this problem?
