सही विकल्प 1 है

अवधारणा:

संचरित AM तरंग की शक्ति इस प्रकार दी गई है:

\(P_t = {P_c}\left( {1 + \frac{{{μ ^2}}}{2}} \right)\)

\(P_t = {P_c} + P_c\frac{μ ^2}{2}\)

वाहक में शक्ति = Pc

दोनों साइडबैंड में शक्ति निम्न द्वारा दी गई है:

\(P_s= \frac{{{P_c}{μ^2}}}{2}\)

चूंकि शक्ति को साइडबैंड के बाईं और दाईं ओर समान रूप से वितरित किया जाता है, साइडबैंड में से एक में शक्ति इस प्रकार दी जाती है:

\(P_{s1}= \frac{{{P_c}{u^2}}}{4}\) ............(1)

स्पष्टीकरण:

दिया गया मॉड्यूलेशन इंडेक्स 1 है

समीकरण 1 में मॉडुलन सूचकांक =1 रखने पर हमें प्राप्त होता है

\(P_{s1}= \frac{{{P_c}{1^2}}}{4} = \frac{{{P_c}{}}}{4}\)

इसलिए साइडबैंड की शक्ति वाहक शक्ति का एक-चौथाई है।
