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 difference between analog and digital modulation Does it depends on baseband signal?

The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.

What is Modulation index in amplitude modulation?

Themodulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level

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.

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.

What is analog digital hybrid modulation?

—Analog digital hybrid modulation seeks the ways to eliminate the incoherent quantization noise component in digital communication, instead of conveniently making it minimal.

Difference between analog modulation and digital modulation?

Analog is when audio or video is taken and translated into electronic pulses. Digital modulation is when audio or video is broken into binary codes and then transferred to the viewing device.
