The modulation index in AM can range from zero to any number. But
if distortion is to be avoided, then the index must not exceed 100%.

What is Modulation index formula in Frequency modulation?
mf=(K*Am)/fm where K: is a proprtionality coefficient Am: is amplitude of the message fm=frequency of modulation
What is percentage power saving if AM transmitter with modulation index m equals 0.5 is replaced by SSBSC transmitter with same modulation index?
Pt=Pc+2Psf, m=0.5 ,Psf=0.0625, saving in power is 100-6.25 % = 94.75%
Difference between delta modulation and differential pulse code modulation?
Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.
How Phase modulation and frequency modulation are inseparable?
both are related because phase is an integral function of frequency
What type of modulation is used to carry the picture portion of a television signal?
Amplitude Modulation (AM) is used for the picture portion of a television transmission while Frequency Modulation (FM) is used for the audio portion.
What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
How the modulation index varies for FM?
how modulation index varies for FM
How modulation index varies for FM?
how modulation index varies for FM
What is Modulation index in Frequency modulation?
Modulation Index is the ratio of the maximum deviation frequency to the frequency of modulation. In other words it is the ratio of the spread in frequency spectrum to the frequency that was used to modulate the carrier. For FM, modulation index is given by the formula mf= df/f where, mf=modulation index for FM df=difference in carrier frequency f=frequency of the signal
The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.
What is the relationship between frequency modulation and the frequency carrier to the modulation index in the AM modulation?
fc>2fm
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
Can modulation index be negative?
ya, it can be negative because as m=Vm/Vc , the value of Vm if taken in negative then modulation index can be naegative
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.
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
Define modulation and modulation index?
a measure of the degree of frequency modulation expressed numerically for a pure tone modulation as the ratio of the frequency deviation to the frequency of the modulating signal.
