The peak frequency deviation
WebbFrequency Deviation (FM) The frequency deviation setting represents the peak variation in frequency of the modulated waveform from the carrier frequency. When the carrier is PRBS, frequency deviation causes a change in the bit rate equal to one-half of the set frequency. For example, a 10 kHz deviation is equivalent to a 5 KBPS change in bit rate. Webb∆f: peak frequency deviation of the transmitter. Am: peak value of the modulating signal Example: Given m(t) = 4cos(2π4x103t) as the message signal and a frequency deviation constant gain (kf) of 10kHz/V; Compute the peak frequency deviation and modulation index! fm=4kHz ∆f= 10kHz/V * 4V = 40kHz. βf = 40kHz / 4kHz = 10 Answer:
