Question

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:

G1 Physics · Accepted Answer

A(c)+A(m)=120 and A(c)−A(m)=80, giving A(c)=100 V and A(m)=20 V. Modulation index μ = A(m)/A(c)=0.2. Amplitude of each sideband = μA(c)/2 = 10 V.
