Question

In the modulation index is 80%, then, power in each sideband is x% of that in the central carrier band. Here, ‘x’ is equal to,

(1) 0

(2) 16

(3) 20

(4) 32

Answer 1

Correct option: (2) 16

Explanation: 

Power carried by the central carrier wave 

Power carried by each sidebands 

Therefore, at 80% modulation.
