Question

A circuit has a gain of 11.3 dB. What is this gain in terms of the power ratio? (Enter your rounded answer to two decimal places.)

Answer 1

To find the power ratio corresponding to a gain of 11.3 dB, we use the formula 10^(Gain in dB/10), which gives us a power ratio of approximately 13.49 when rounded to two decimal places.

Step-by-step explanation:

The student asked about the power ratio corresponding to a gain of 11.3 dB in a circuit. To calculate the power ratio from decibels (dB), we use the formula:

Power Ratio (P2/P1) = 10^(Gain in dB/10).

For a gain of 11.3 dB, the power ratio would be:

Power Ratio = 10^(11.3/10) = 10^(1.13) ≈ 13.49.

Rounded to two decimal places, the power ratio is 13.49.
