36.
The amplitude modulated wave is given by __________ e = 25(1 + 0.7 cos 5000t - 0.3 cos 1000t) x sin 5 x 106t The amplitude of carrier and sideband frequencies in magnitudes are
Answer: Option
Explanation:
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
