Detailed Solution
Download Solution PDFसंकल्पना:
AM सिस्टमसाठी एकूण प्रसारित शक्ती याद्वारे दिली जाते:
\({P_t} = {P_c}\left( {1 + \frac{{{μ^2}}}{2}} \right)\)
Pc = वाहक शक्ती
μ = मॉड्यूलेशन इंडेक्स
वरील अभिव्यक्ती प्राप्त करण्यासाठी विस्तारित केली जाऊ शकते:
\({P_t} = {P_c} + P_c\frac{{{μ^2}}}{2}\)
एकूण शक्ती ही वाहक शक्ती आणि साइडबँड शक्तीची बेरीज आहे, म्हणजे.
\({P_s} = P_c\frac{{{μ^2}}}{2}\)
गणना:
दिलेले आहे: Pc = 1000 W आणि μ = 0.8.
आपण लिहू शकतो:
\({P_s} = P_c\frac{{{μ^2}}}{2}\)
\(= 1000 \times \frac{0.8^2}{2}\)
\(P_s=320~W\)
एकूण साइडबँड पॉवर = 320 W
वरच्या साइडबँडमधील पॉवर + लोअर साइड बँडमधील पॉवर = 320 W
वरच्या साइडबँडमधील पॉवर = लोअर साइडबँडमधील पॉवर = 160 W
