4.13-3 Keep the same m1 (t) and fc= 500 Hz in Problem 4.13-1. Following the example in Section 4.12.3, numerically generate the following figures: \text { (b) The signal }

e(t)=2 s(t) \cos 2 \pi f_{c} t \text { in time and frequency response. } (c) The recovered message signal in time domain. \begin{array}{llll} \text { (a) Lower sideband SSB-SC } & \text { amplitude } & \text { modulation signal } s(t)=m_{1}(t) \cos 2 \pi f_{c} t+ \end{array} m_{1 h}(t) \sin 2 \pi f_{c} t \text { in time domain and frequency domain. }
