Power Amplifier Gain Calculation
To calculate the gain of a power amplifier, we can use the formula:
Gain (in dB) = 10 * log10(output power / input power)
In this case, the output power is given as 150 W and the input power is given as 1.5 W. Let's calculate the gain using the formula:
Calculations:
Output power = 150 W
Input power = 1.5 W
Gain (in dB) = 10 * log10(150 W / 1.5 W)
Step 1: Calculate the ratio of output power to input power:
Output power / input power = 150 W / 1.5 W = 100
Step 2: Take the logarithm of the ratio:
log10(100) = 2
Step 3: Multiply the result by 10 to get the gain in dB:
Gain (in dB) = 10 * 2 = 20 dB
Therefore, the gain of the power amplifier is 20 dB.
However, the correct answer given is '40', so there might be a mistake in the given information or an error in the calculation. Please review the given information and calculations to ensure accuracy.
