Question
Select the correct statement that describes what you see in the plots:
a. The signal, s(t), is distorted by the dramatic change in message frequency.
b. The message amplitude change can be seen in the signal plot of s(t). When comparing plots for s(t) and m(t), it is obvious that the signal accurately represents the message.
c. Both the message and carrier frequencies increase, therefore distortion will be experienced.
d. The phase of the signal has shifted to the right, because AM techniques impact phase and amplitude.

b)The message amplitude change can be seen in the signal plot of s(t). When comparing plots for s(t) and m(t), it is obvious that the signal accurately represents the message
Explanation:
From figure of s(t) we can see that the carrier wave amplitude is changed in accordance with the message m(t) i.e. Amplitude modulation (AM) the amplitude modulated signal accurately represents the message signal.No phase is impacted in amplitude modulation
