QJEEM23Ph9a83: JEE Main 2023 Physics - Class 12 JEEM23Ph9a83 Solution: A sinusoidal carrier voltage is amplitude modulated. The…

A sinusoidal carrier voltage is amplitude modulated. The resultant amplitude modulated wave has maximum and minimum amplitude of 120 V and 80 V respectively. The amplitude of each sideband is :

Multiple Choice Options

  • A 15 V
  • B 20 V
  • C 5 V
  • D 10 V

Step-by-Step Verified Solution

Amplitude of each side band = Amessage2

Acarrier+Amessage=120 ............ (1)

Acarrier−Amessage=80 .............. (2)

From (1) and (2)

Amessage=20 V

∴ Amplitude of each side band = 10 V
