An AM wave has \(1800 \mathrm{~W}\) of total power content for \(100 \%\) modulation the carrier should have power content equal to
- A \(1000 \mathrm{~W}\)
- B \(1200 \mathrm{~W}\)
- C \(1500 \mathrm{~W}\)
- D \(1600 \mathrm{~W}\)
Answer & Solution
Correct Answer
(B) \(1200 \mathrm{~W}\)
Step-by-step Solution
Detailed explanation
Total power of AM wave, \(P_t=1800 \mathrm{~W}\) For \(100 \%\) modulation, depth of modulation, \(m=1\) If \(P_c\) be the carrier power, then we know that,…
