HomeWhat is frequency modulation?
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.

FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
in frequency modulation, frequency of carrier signal changes. so frequency variations of carrier convey all the information in frequency modulation.
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.
Modulation schemes depends on frequency.
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
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.

phase modulation can be applied instead of frequency modulation as it has almost same advantages to that of frequency modulation.but in case of frequency modulation the clarity is more.it is used in America foe radio communication.
