1.	At 100% modulation, let the total power in the sidebands be x% of the total power of the amplitude modulated wave. Here, ‘x’ is equal to, (1) 25 (2) 33.3 (3) 75 (4) 100
Answer» Correct option: (2) 33.3 Explanation: Fraction of total power carried by the sidebands = m²/2 + m² Therefore, at 100% modulation, sidebands carry only 1/3rd of the total power.

Answer»

Correct option: (2) 33.3

Explanation:

Fraction of total power carried by the sidebands = m²/2 + m²

Therefore, at 100% modulation, sidebands carry only 1/3rd of the total power.
