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-A-4 x 104 HzB-2 x 106 HzC-2 x 109 HzD-2 x 1010 Hz-B-2 x 106 Hz

Question

APTITUDE CRACK · Accepted Answer

B 2 x 106 Hz Bandwidth = 2&Delta;f + 2B But for NBFM, B &lt; 1 BW &asymp; 2fm 2fc1 2 x 106 Hz.
