Question

In AM modulation, a signal is modulated on a carrier wave such that maximum and minimum amplitude are found to be 6 V and 2 V respectively. The modulation index is, 100 %, 80 %, 60 %, 50 %

MARKS App · Accepted Answer

Given here, V max = 6 V and V min = 2 V Now, modulation index = V max - V min V max + V min . × 100 % = 6 - 2 6 + 2 × 100 % = 50 %
