Chapter 1, Problem 1.28IP

Power Ratio (PR) in dB
A stereo amplifier takes the output of a CD player, for example, and increases the power to an audible level. Suppose the output of the CD player is 25 mW and the desired audible output is 100 W per stereo channel, find the power ratio of the amplifier per channel in decibels (dB), where the power ratio in dB is P R db = 10 log 10 ( p 2 / p 1 )
