WebbThe peak-to-peak frequency deviation (2 f). A Carrier Swing. 14 Q The ratio of the frequency deviation actually produced to the maximum frequency deviation allowed by law stated in percent form. A Percent Modulation. 15 Q A rule which is an approximation and gives transmission bandwidths that are slightly narrower than the bandwidths. 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… Webb13 sep. 2024 · As such the modulation index of an FSK signal is defined as the ratio of the frequency deviation of the modulated signal to the bandwidth of the modulating signal (or the message).
