WebbThe carrier signal frequency is 1kHz, the modulating frequency 100Hz, and the modulation index is 3. Taking note of the modulation index, this makes the peak frequency deviation 300Hz. The frequency will swing between 700 and 1300 Hz. On the other hand, the function of the modulating frequency is to know how fast the cycle is completed. Frequency deviation () is used in FM radio to describe the difference between the minimum or maximum extent of a frequency modulated signal, and the nominal center or carrier frequency. The term is sometimes mistakenly used as synonymous with frequency drift, which is an unintended offset of an oscillator from its nominal frequency. The frequency deviation of a radio is of particular importance in relation to bandwidth, because l… WebbWhat is the frequency deviation produced by noise if the modulating frequency is 400 Hz and the phase difference introduced by noise is 0.43 rad? ...
