AIIMS 2018 Physics Amplitude Modulation MCQ Question

The amplitude of a modulated signal is calculated as half the difference between the maximum and minimum amplitudes. Here, the maximum amplitude is 15 V and the minimum amplitude is 5 V, so the amplitude is given by $(15 \, \text{V} - 5 \, \text{V}) / 2 = 10 \, \text{V}$. Options B (20 V), C (30 V), and D (40 V) do not represent the correct calculation of amplitude, as they do not account for the average of the maximum and minimum values.
