For AM (amplitude modulation) signals, it is the ratio (x100 of course) of the modulating signal to the carrier signal. presumably FM calculations follow a similar course.

What is the modulation index called when it is expressed as a percentage?

When the modulation index is expressed as a percentage, it is commonly referred to as the "percentage modulation." This representation indicates the extent of modulation in relation to the carrier signal, showing how much the amplitude of the carrier varies due to the modulating signal. It provides a clearer understanding of modulation depth for practical applications in communication systems.

Why a high percentage of modulation is desirable?

Is important to use as high a percentage modulation as possible while ensuring that overmodulation does not occur. The side bands contain the information and have maximum power at 100% modulation. And AM transmiters attempt to maintain betwen 90 and 95 percent modulation as a compromise between efficiency and the change of drifting into into overmodulation. sources page 76 second paragraph of the MODERN ELECTRONIC COMUNICATION By Jeffrey S.Beasley and Gary M.Miller


What do you mean by depth of modulation index?

The depth of modulation index refers to the extent to which a carrier signal is varied by a modulating signal in amplitude modulation (AM). It is typically expressed as a percentage and indicates how much the amplitude of the carrier wave changes in response to the modulating signal. A modulation index of 100% means full modulation, where the carrier's amplitude varies completely with the modulating signal. Values above 100% can lead to distortion and over-modulation, impacting the quality of the transmitted signal.


What transmmited power when modulation index 0 to 1?

It can be anything at all, from yoctowatts to terawatts. You must state the power output at some modulation index before I can calculate it for some other modulation index. By the way . . . the answer also depends on the method of modulation, which you have not mentioned. For example, with pure FM, the transmitted power doesn't change, regardless of the mod-index.
