A3. A signal ST consists of the sum of three sinusoids with frequencies of 20Hz, 40Hz and 130Hz respectively. All three sinusoids have an amplitude of 500pV and zero phase shift. I. II. Write the Fourier series for the signal ST. [4 marks] The signal is sampled at 1024Hz and a 256-point DFT is computed on the discrete signal. Sketch the signal amplitude spectrum as produced by the DFT and account for its shape. [6 marks] A3.
