A modulation index of 0.5 would be same as

A modulation index of 0.5 would be same as Modulation depth is typically the modulation index expressed as a percentage of the figure. Thus a modulation index of 0.5 is expressed as a modulation depth of 50%. However, often the two terms and figures may be used interchangeably.

1. What does the modulation index of 0.5 refer to?
2. When the modulation index of an AM wave is increased from 0.5 to 1 the transmission power?
3. What is the value of modulation index?

What does the modulation index of 0.5 refer to?

The interpretation of the modulation index, m, may be expressed as: The fraction (percentage if multiplied by 100) of the carrier amplitude that it varies by. If m = 0.5, the carrier amplitude varies by 50 % above and below its original value.

When the modulation index of an AM wave is increased from 0.5 to 1 the transmission power?

The transmitted power is. Increased by 50 percent.

What is the value of modulation index?

Its value is generally kept less than 1 for practical purposes to avoid over modulation which leads to distortions in the modulated signal and then makes it very hard to demodulate and extract the modulating signal.
