FM Modulation Index and Frequency trippler

1. What will be the modulation index of the wave at the output of a frequency tripler if the input is an FM wave with modulation index m1?
2. What is the modulation index of FM?
3. How does modulation index affect FM?
4. What is the bandwidth needed for FM system if peak deviation is of 3 kHz and handles signal of 5kHz?

What will be the modulation index of the wave at the output of a frequency tripler if the input is an FM wave with modulation index m1?

In FM signal with a modulation index mf is passed through a frequency tripler. The wave in the output of the tripler will have a modulation index of. 1.

What is the modulation index of FM?

The frequency modulation index is mostly over 1 and it usually requires a high bandwidth at a range of 200 kHz. FM operates in a very high-frequency range normally between 88 to 108 Megahertz.

How does modulation index affect FM?

The modulation index affects the modulated sinusoid in that the larger the modulation index, the greater the instantaneous frequency can be from the carrier. Below we illustrate an FM modulated signal in which the center frequency is 500 kHz.

What is the bandwidth needed for FM system if peak deviation is of 3 kHz and handles signal of 5kHz?

For example, a typical VHF/UHF two-way radio signal using FM mode, with 5 kHz peak deviation, and a maximum audio frequency of 3 kHz, would require an approximate bandwidth of 2 * (5kHz + 3kHz) = 16 kHz.
