Detailed Solution
Download Solution PDFसंकल्पना:
dBm हे मापनाचे एकक आहे जे एका निश्चित संदर्भ पातळीच्या संदर्भात शक्ती पातळीचे गुणोत्तर दर्शवण्यासाठी वापरले जाते.
dBm सह, संदर्भ पातळी 1 mW (मिलीवॅट) आहे.
dBm मधील शक्ती खालीलप्रमाणे व्यक्त केली जाते:
\(P(dBm)=10log_{10}(\frac{P}{1m})\)
P = dBm मध्ये व्यक्त करण्याची शक्ती
अनुप्रयोग:
दिलेल्याप्रमाणे, dBm मध्ये आउटपुट पॉवर = 50
\(50=10log_{10}(\frac{P}{1m})\)
\(5=log_{10}(\frac{P}{1m})\)
दोन्ही बाजूंना अँटिलॉग घेतल्यास, आपणास मिळते:
\(10^5=\frac{P}{1m}\)
P = 105 × 10-3 W
P = 100 W
