Amplitude modulation

What is Amplitude Modulation?

• A process where the frequency of a carrier signal changes with respect to a message signal.

• A process where the phase of a carrier signal changes with respect to a message signal.

• A process where the amplitude of a carrier signal changes with respect to a message (modulating) signal.

• A process where both the frequency and amplitude of a carrier signal change simultaneously.

In Amplitude Modulation, what determines the change in the carrier signal's amplitude?

• The frequency of the carrier signal.

• The amplitude of the modulating signal.

• The phase of the modulating signal.

• The power of the carrier signal.
