In an amplitude modulated signal the maximum amplitude is 15 volt and minimum amplitude is 5 volt, then amplitude of modulating wave will be

Options

  1. A10 ~V
  2. B5 ~V
  3. C20 ~V
  4. D30 ~V

Correct answer

A. 10 ~V

Step-by-step solution

Maximum amplitude =A_m+A_C=15 minimum amplitude =A_m-A_C=5 So 2 A_ m =20 ; A_m=10 ~V
