FM Deviation? QRZ Forums
The maximum frequency deviation for an FM signal is different from the bandwidth of the FM signal which is technically infinite since the sidebands extend out to $\pm\infty$, though most of the energy is in the vicinity of the carrier frequency (the sidebands taper off rapidly) and so measures such as "$99\%$ energy containment" bandwidth are much smaller. For example, in the US, FM signals... What is the deviation ratio for an FM phone signal having a maximum frequency deviation of plus or minus 5 kHz and accepting a maximum modulation rate of 3 kHz? 1.66 What is the deviation ratio of an FM-phone signal having a maximum frequency swing of plus or minus 7.5 kHz and accepting a maximum modulation rate of 3.5 kHz?

ANALYSIS OF THE FM SPECTRUMSPECTRUM

In most communications systems using FM, maximum limits are put on both the frequency deviation and modulating frequency. For example, in standard FM broadcasting, the maximum permitted frequency deviation is 75 KHz, while the maximum permitted modulating frequency is 15 KHz. This produces a modulation index of...
Usually, you'll have some common combinations of maximum modulating frequency and deviation. For example, in 5 kHz systems, it's not uncommon to have a 3 kHz set as maximum audio frequency. From my interpretation of the quote in the question, I'd say that this are the 3 kHz it's talking about.

How To Find Maximum Frequency Derivation Of Fm Signal

Calculate the peak frequency deviation of the FM carrier using Carson’s rule. Answer: Carson’s rule gives the bandwidth of an FM signal in terms of the peak frequency deviation, ∆f pk, and the maximum baseband frequency, f max .

  • Where Fd is the frequency deviation and Fmax is the maximum frequency content of the signal. For example, for a sine wave of frequency 5k Hz and modulated with a frequency deviation of 10k Hz will have an approximate bandwidth of 30k Hz.
  • 14.The bandwidth of an FM signal is proportional to the _____. 15.The maximum frequency deviation of an FM signal is 10 kHz. The maximum modulating frequency is 3.33 kHz.
  • 5. A 10 MHz carrier is frequency modulated by a sinusoidal signal of 500 Hz, the maximum frequency deviation being 50 KHz. The bandwidth required.
  • Note that deviation and modulation frequency are in the same units of frequency (KHz, MHz, etc). In general, the higher the value of β the better the signal to noise ratio of an FM
