When the frequency sensitivity of the modulating signal is small,the bandwidth of the FM is narrow.
The narrowband FM has one carrier term two sideband terms.The modulation index is also small compared to one radian.

What is significance of upper frequency band and lower frequency band with reference to Amplitude modulation?
waht si a picture of signification
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
What does am frequency stand for?
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.
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
Why is intermediate frequency transformer used in amplitude modulation?
used as a adjustable band pass filter...
A modulated waveform that contains a carrier plus two sidebands for each modulation frequency is a description of?
Both AM and narrow-band-FM.

What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.

AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.

What is the difference between frequency modulation and phase 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.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
What is Modulation index in Frequency 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
What is the meaning of FM in FM Radio?
FM means frequency modulation AM means amplitude modulation

What is the relationship between frequency modulation and the frequency carrier to the modulation index in the AM modulation?
fc>2fm
