Only answer question 3. The information for 1 is provided because it is needed for 3.

in Matlab make a discrete time version of the pulse train in #1 given a sample rate, f,- 10*fo and take its FFT. Plot the time domain and frequency domain results and label the x & y axes appropriately. 3. Derive an expression for complex Fourier series coefficients, Sk, for a square pulse train with a frequency of 30.72MHz and an amplitude of A. What are the frequencies and amplitude values of the DC term and the first three harmonics? 1
