Depth of modulation (ma)\left( {{m_a}} \right) in terms of Emax and Emin{{\text{E}}_{{\text{max}}}}\,{\text{and}}\,{{\text{E}}_{{\text{min}}}} is
View answer and explanation
Correct option: C
ma = Emax - Emin/Emax+Emin{{\text{m}}_{\text{a}}}{\text{ = }}{{\text{E}}_{{\text{max}}}}{\text{ - }}{{\text{E}}_{{\text{min}}}}{\text{/}}{{\text{E}}_{{\text{max}}}} + {{\text{E}}_{{\text{min}}}}
Option C (ma = Emax - Emin/Emax+Emin){{\text{m}}_{\text{a}}}{\text{ = }}{{\text{E}}_{{\text{max}}}}{\text{ - }}{{\text{E}}_{{\text{min}}}}{\text{/}}{{\text{E}}_{{\text{max}}}} + {{\text{E}}_{{\text{min}}}}) is correct because it is the standard formula for calculating the depth of modulation in terms of maximum and minimum amplitudes.
