A message signal with bandwidth 10 kHz is lower sideband SSB modulated with carrier frequency fc1 = 106 Hz. The resulting signal is then passed though a narrow band frequency modulator with carrier frequency fc2 = 109 Hz. The bandwidth of the output would be
Answer: Option
Explanation:
Bandwidth = 2Δf + 2B
But for NBFM, B < 1
BW ≈ 2fm 2fc1 2 x 106 Hz.
