Answer 2

Explanation:

Amplitude modulation:-

When the amplitude of a high frequency carrier wave is changed in accordance with the intensity of signal is called amplitude modulation .

Frequency modulation (FM) :-

In a frienquency modulation , frequency carrier wave is modified in accordance with the amplitude of the nodulation wave .

Pulse code modulation (PCM) :-

when the pulse of a hight frequency carrier wave is changed in accordance with the intestesity of signal is called pulse code modulation .
