Best Answer

frequency modulation stands for FM (on your radio).

Better Answer

"frequency modulation stands for FM"

No it doesn't. On the contrary, f.m. stands for frequency modulation.

Frequency modulation is the method of impressing information on an r.f. carrier by changing its frequency back and forth in sympathy with the informatiion signal.

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 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

Comparison of amplitude modulation and frequency modulation?
