In an amplitude modulated signal the maximum amplitude is 15 V and minimum amplitude is 5 V. The amplitude of modulating wave will be
  1. 5V
  2. 10V
  3. 20V
  4. 30V

Solution

Maximum amplitude Am+Ac=15 V

Minimum amplitude Am-Ac=5 V

                                                            
⇒2Am=20 V

Amplitude of modulated wave, Am=10 V
