Detailed Solution
Download Solution PDFसंकल्पना:
अपेक्षित शक्ति स्तर = इनपुट शक्ति – हानि + कुल लाभ
नोट: dB में, लाभ को केवल जोड़ा जाता है।
dBm को dBW में परिवर्तित करने के लिए और इसके विपरीत:
P(dBm) = P(dBW) + 30
गणना:
दिया गया है:
इनपुट शक्ति = -10 dBm
- 10 = P + 30
इनपुट शक्ति = -40 dBW
कुल हानि = – 2 – 3 – 5 = –10 dB
कुल लाभ = 20 + 30 = 50 dB
अपेक्षित शक्ति स्तर निम्न होगा:
= –40 – (2) + 30 – (3) + 20 – 5 = 30 dBW
P(dBm) = 0 + 30
∴ 30 dBm सही उत्तर होगा।
