A signal m(t) modulates a 100 kHz carrier to produce the following narrowband FM signal:
ΦNBFM(t) = 5 cos (2π 105t + 0.0050 sin 2π × 104t)
The signal is converted to wideband FM signal by passing through the system shown below. If the carrier frequency at the output is 120 MHz then the frequency of local oscillator circuit is: _________ MHz
