Just these 2 questions thank you! 2. ( 2 points) Find the exponential Fourier series coefficients of the following signals and plot their amplitude and phase spectra. Note that no integration is needed to solve the problem. (a) x1(t)=2+ 4cos(3t)2jsin(7t) (b) x2[n]=4cos(2.4n)+2sin(3.2n) 3. (6 points) Consider the following periodic signal x(t) : Determine: (a) The exponential Fourier series representation. (b) The trigonometric Fourier series representation. BJksDRPrf96kfrB1XsIog 1 (c) The compact Fourier series representation. (d) Use the results to find the exponential Fourier series coefficients of the periodic signal g(t) below..
