An amplitude modulated wave is as shown in the figure the value of peak carrier voltage and value of peak information voltage are respectively.

A
30 V, 20 V
B
10 V, 15V
C
15 V, 30 V
D
20 V, 25 V
Answer
30 V, 20 V
Explanation
Solution
:

From figure
Vmax=2100=50⇒Vmin=220=10V
Peak carrier voltage
Vc=2Vmax+Vmin=250+10=30 V
Modulation index
Peak information voltage,
Vm=μVc=32×30=20V
