MATLAB: Am modulation

Question

message signal will be loaded then modulated using AM standard Modulation and AM suppressed Carrier modulation (one at a time). Fc (2000-11000) Hz Modulation index (0-1) The message signal should be shown in the time domain and frequency domain. The modulated signal should be shown in the time domain and frequency domain. The Modulating signal should be shown in the time domain and frequency domain. The Demodulated signal should be shown in the time domain and frequency domain. Play the message signal and demodulated signal. One axes plot will be used.
