SOLUTION: The signal ratio (S) in decibels of am amplifier is modeled by S=10 log (P output/P input). If an amplifier gains 13 dB with an input of 9.8 W, what is the output power in W?

The signal ratio (S) in decibels of am amplifier is modeled by S=10 log (P output/P input).
If an amplifier gains 13 dB with an input of 9.8 W, what is the output power in W?
= 13
=
= 1.3
find the antilog of both sides
= 19.952
Po = 9.8 * 19.952
Po = 195.5 watts, output power
