An amplitude modulated voltage is expressed as

e = 10\left( {1 + 0.8\,\cos \,2000\,\pi t} \right)\cos \,3 \times {10^6}\,\pi t\,{\text{volt}}

. The peak
voltage of carrier wave is

View answer and explanation

Correct option: C

10V

Option C (10V) is correct because the peak voltage of the carrier wave is the coefficient outside the parenthesis in the given amplitude modulated voltage expression.
