The peak frequency deviation
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… WebbThe peak frequency deviation is determined from Equation 14: 1 kHz b. The minimum bandwidth is determined from Equation 15: B 2(1000 2000) 6 kHz c. For FSK, N 1, and the baud is determined from Equation 11 as baud 2000 1 2000 ¢ f 49kHz 51kHz 2 baud fb 1 fb Digital Modulation binary frequency input output
