The amplitude of the side bands of the modulated signal if the carrier signal and message signal amplitudes are 25 ~V and 5 ~V respectively is
Options
- A0.5 ~V
- B2.5 ~V
- C0.2 ~V
- D5 ~V
Correct answer
B. 2.5 ~V
Step-by-step solution
We have m = A _ m A _ c = 5 25 = 1 5 So, amplitude of side band = mA _ C 2 = 1 5 1 2 25=2.5 ~V
