is zero outside of the displayed time interval): The input to this filter is the following periodio cignal se (T- T The dashed line shows one isolated period. Answer the following, 1. Determine the Fourier series for the periodic inputs. In particular, derive an expression for the Fourier series coefficients. 2. Determine the frequency response of the moving average filter. Hint: compute the Fourier transform of the impulse response. 3. Determine the Fourier series coefficients for the periodic output p 4. Use Matlab to compute a partial sum of the Fourier series for y with -1000,-900,1,0,1,999, 1000 on the time grid t = [-3:0.001:3]. Compare this result to the graphical convolution ap- proach from Homework 3.
