Amplitude of a Wave

Q. Amplification is done to compensate for the loss occured due to attenuation.

1. True
2. False

Q. In amplitude modulation, the amplitude of the carrier wave is varied in proportion to that of the message signal being transmitted.

1. False
2. True

Q. For amplitude modulated wave, carrier frequency should be message frequency.

1. greater than
2. equal to
3. lesser than

Q. A signal of frequency $10\text{kHz}$ and peak voltage of $10\text{V}$ is used to modulate a carrier of frequency $800\text{kHz}$ and peak voltage of $20\text{V}$. What is the amplitude modulation index?

1. $0.5$
2. $2.5$
