What is Modulation index formula in Frequency modulation?
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.
What is percentage power saving if AM transmitter with modulation index m equals 0.5 is replaced by SSBSC transmitter with same modulation index?
The percentage power saving when replacing an AM transmitter with modulation index of 0.5 with an SSBSC transmitter with the same modulation index would be approximately 93.75%. This is because SSBSC transmitters only transmit one sideband, while AM transmitters transmit both sidebands, resulting in less power usage and more efficiency.
In FM does the amplitude remains constant?
In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
What are the charateristics of amplitude modulation?
Amplitude modulation (AM) is a method of impressing data onto an alternating current waveform by varying its amplitude in relation to the data being sent. The main characteristics of AM include the modulation index, which determines the amount of variation in the carrier wave, and the sidebands that are created as a result of modulation. AM is susceptible to noise and interference due to its reliance on the amplitude of the signal.
What is the relation between susceptibility and nonlinear refractive index?
The susceptibility of a material describes its response to an external electric field, while the nonlinear refractive index relates to the change in refractive index with intensity of light. In some cases, the nonlinear refractive index can be related to the third-order susceptibility of a material when considering nonlinear optical effects such as self-focusing or self-phase modulation.
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?

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
What is Modulation index formula in Frequency modulation?
The modulation index formula in frequency modulation (FM) is given by the equation: β = Δf / fm, where β is the modulation index, Δf is the peak frequency deviation, and fm is the modulating frequency. Modulation index indicates how much the carrier frequency is being varied by the modulating signal in FM.
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
