Question:
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 \(25 \mathrm{~mW}\) and the desired audible output is 100 \(\mathrm{W}\) per stereo channel, find the power ratio of the amplifier per channel in decibels ( \(\mathrm{dB}\) ), where the power ratio in \(\mathrm{AB}\) is
\[
P R_{\mathrm{dB}}=10 \log _{10}\left(p_{2} / p_{1}ight)
\]
