एक आयाम मॉडुलित तरंग का अधिकतम आयाम \( 25 \mathrm{~V} \) तथा न्यूनतम आयाम \( 5 \mathrm{~V} \) है। इसका मॉडुलन सूचकांक होगा-
[Hint : \( \left.m=\frac{E_{\max }-E_{\min }}{E_{\max }+E_{\min }}=\frac{25-5}{25+5}=\frac{2}{3}\right] \)
(A) \( \frac{1}{5} \)
(B) \( \frac{1}{3} \)
(C) \( \frac{3}{2} \)
(D) \( \frac{2}{3} \)
