Question

Calculate the modulation percentage if the modulating signal is 8 V and carrier is of 12 V?
1. 50
2. 67
3. 150
4. 33

Answer 1

Correct Answer - Option 2 : 67

Data:

modulating signal = V_m = 8 V

carrier signal = V_c = 12 V

Formula:

Modulation percentage = \(\frac{V_m}{V_c} \times 100\)

Calculation:

Modulation percentage = \(\frac{8}{12} \times 100\)

∴ Modulation percentage = 66.66 ≈ 66.67
