Question: Select the correct statement regarding the difference between the FM modulated signal waveform and the AM modulated signal waveform. a. The FM signal wave changes

Select the correct statement regarding the difference between the FM modulated

Select the correct statement regarding the difference between the FM modulated signal waveform and the AM modulated signal waveform.

		a. The FM signal wave changes frequency according to the message wave m(t). The "peak" amplitude of the FM signal, Ac=5, remains constant. This is because m(t) does not modulate the amplitude of the carrier wave when using FM techniques.
		b. There is no difference between the FM and AM signal waves because they are both modulated by the same message wave, m(t) = A_mcos(2f_mt)
		c. The AM signal wave frequency changes with the message wave m(t) while the amplitude of the FM signal changes with m(t).
		d. All statements are correct.
