Q: In MATLAB, make time-domain graphs of a Conventional DSB AMsignal u(t) = A_c[1 + am(t)]cos(2×π×f_c×t), with A_c = 1, m(t) =cos(2×π×f_m×t), f_c = 1 kHz, f_m = 50 Hz, for four cases of AMmodulations: a = 0, a = 0.3, a = 1, a = 1.3. Your graphs should beover four periods of the message (i.e., 0 < t < 4/fm).Include your code in your solution as well as the four graphs.
