Question

In an amplitude modulated signal the maximum amplitude is 15 volt and minimum amplitude is 5 volt, then amplitude of modulating wave will be (A) 10 V (B) 5 V (C) 20 V (D) 30 V

Tardigrade Admin · Accepted Answer

Maximum amplitude = Am + AC = 15 minimum amplitude = Am - AC = 5 So 2Am = 20; Am = 10 V

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

10 V

5 V

20 V

30 V

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