(0.5 pts) In Matlab make a discrete time version of a square pulse train with a frequency of $$20\mathrm{MHz}$$ and an amplitude of 5, with a sample rate, $$f_s=10f_o$$ and take its FFT. What are the frequencies and amplitude values of the DC term and the first three harmonics? Plot the time domain and frequency domain results and label the $$x\&y$$ axes appropriately. For the time domain plot, show 3 or 4 symbols only rather than the entire pulse train.
