Question
Calculate the power gain in decibels for each of the following cases.a. $P_{o}=100 \mathrm{~W}, P_{i}=5 \mathrm{~W}$.b. $P_{o}=100 \mathrm{~mW}, P_{i}=5 \mathrm{~mW}$.c. $P_{o}=100 \mathrm{~mW}, P_{i}=20 \mu \mathrm{W}$.
Step 1
The formula is: Power Gain (dB) = 10 * log10(Po / Pi) where Po is the output power and Pi is the input power. Now, let's calculate the power gain for each case: a. Po = 100 W, Pi = 5 W Power Gain (dB) = 10 * log10(100 / 5) = 10 * log10(20) ≈ 10 * 1.301 = 13.01 Show more…

Calculate the power gain in decibels for each of the following cases. a. Po = 100 W, Pi = 5 W. b. Po = 100 mW, Pi = 5 mW. c. Po = 100 mW, Pi = 20 μW. Determine GdBm for an output power level of 25 W. Two voltage measurements made across the same resistance are V1 = 110 V and V2 = 220 V. Calculate the power gain in decibels of the second reading over the first reading.
An amplifier has an input power of 5 mW. The output power is 100 mW. What is the decibel gain to the nearest decibel?
Decibels (Refer to Example 2.) Use the formula $D(x)=10 \log \left(10^{16} x\right)$ to determine the decibels when the intensity of a sound is $x=10^{-1 / 2}$ watt per square centimeter.
