Question

Quizplus · Accepted Answer

According to the formula for calculating decibels from power ratio, which is 10 * log10(P2/P1), where P2 is the higher power and P1 is the lower power, a 100/1 increase in power corresponds to a power ratio of 100:1, which is equivalent to 20 decibels (dB). Therefore, the best choice is C, which corresponds to 20 dB.
