What is amplitude and frequency of a wave?

The amplitude is the maximum displacement. The frequency is the number of peaks (or troughs) that occur in unit time (usually a second).


What is narrow band and wide band FM and How it can be generated?

In frequency modulation system, the maximum usable deviation be fixed +- 5 KHz and test deviation be kept 60% i.e. 3 KHz for wireless telephony systems used in military and other organisations. But wide band fm systems used in commercial broadcasts having frequency deviation +- 75 KHz.

What is the meaning of the term frequency swing in reference to a FM broadcast station?

Frequency swing is nothing but the deviation or the frequency change from the reference frequency

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
