Question details

Homework #1 (due 1/22) 1. Compute the Fourier Coefficients for the function f(t) = 0, otherwise 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? 2. Derive an expression for complex Fourier series coefficients, Sk, for a rectangular pulse train where the width of the pulse, τ, is equal to (1/3)*T, what are the freq and amp values of the DC term and first three harmonics? 3. In Matlab make a discrete time version of the pulse train in #2 given a sample rate, fs 10*fo and take its FFT. Plot the time domain and frequency domain results and label the x & y axes appropriately. 4. In Matlab make a discrete time version of the pulse train in #3 given a sample rate, f,- 10% and take its FFT. Plot the time domain and frequency domain results and label the x & y axes appropriately. 5.question5 only
