Time-domain sampling consider the continuous-time signal(a) Compute analytically the spectrum Xa (F) of xa (t).(b) Compute analytically the spectrum of the signal x (n) = xa (nT). T = 1/F.(c) Plot the magnitude spectrum |Xa (F)| for F0 = 10Hz.(d) Plot the magnitude spectrum |Xa (F)| for F0 = 10. 20. 40 and 100 Hz.(e) Explain the results obtained in part (d) in terms of the aliasingeffect.
