1.

The amplitude modulated wave is given by __________ = 25(1 + 0.7 cos 5000 - 0.3 cos 1000) x sin 5 x 10 The amplitude of carrier and sideband frequencies in magnitudes are

Answer» Modulation index is 0.7 and 0.3 so that amplitude of signal is 0.7 x 25 = 17.5 and 0.3 x 25 = 7.5 On modulation the sideband amplitude is . Hence 8.75 and 3.75
