radio stations operating at various frequencies.
The sound signal of a standard NTSC television signal is frequency modulated.
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
Tone modulation through of modulating a carrier frequency using the charactoristics of a sound, its the method used for telephone
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.
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.
AM - Amplitude Modulation FM - 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
FM means frequency modulation AM means amplitude modulation
fc>2fm
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.
AM (Amplitude Modulation) has a smaller bandwidth and can have more stations available in any frequency range. AM is cheaper and can be transmitted over long distances. FM (Frequency Modulation) signals are prone to interference due to physical obstructions. The better sound quality is due to a much higher bandwidth, using FM.
