Question
A transmitter transmit a power of $10 \mathrm{KW}$ when modulation is $50 \%$. What is the power of carrier wave?(A) $12 \mathrm{KW}$(B) $7.0 \mathrm{KW}$(C) $8.89 \mathrm{KW}$(D) $5.0 \mathrm{KW}$
Step 1
The formula is given as: \[ P_{t} = P_{c}(1 + \frac{m^{2}}{2}) \] where \( P_{t} \) is the transmitted power, \( P_{c} \) is the carrier power, and \( m \) is the modulation index. Show more…

When the modulation percentage is 75 , an AM transmitter produces $10 \mathrm{~kW}$. How much of this is carrier power? (a) $10 \mathrm{~kW}$ (b) $13.33 \mathrm{~kW}$ (c) $7.5 \mathrm{~kW}$ (d) $7.81 \mathrm{~kW}$

Round 2
A transmitter transmits a power of 10000 W when the modulation is 50%. Find the power of the carrier wave.
An AM transmitter radiates 9 kW of power when the carrier is unmodulated and 10.125 kW when the carrier is sinusoidally modulated. Find the modulation index, percentage of modulation. Now, if another sine wave, corresponding to 40 per cent modulation is transmitted simultaneously, then calculate the total radiated power.
