D) 26 dB.

Quizplus · Accepted Answer

The closed-loop gain in decibels (dB) is calculated using the formula 20*log10(Vout/Vin), where Vout is the output voltage and Vin is the input voltage. Without the specific circuit details or values, a general understanding is that a gain of 6 dB represents a doubling of the voltage. This choice is selected based on common circuit configurations and their typical gains.
