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?
10%2Alog%28%28Po%29%2F%289.8%29%29 = 13
log%28%28Po%29%2F%289.8%29%29 = 13%2F10
log%28%28Po%29%2F%289.8%29%29 = 1.3
find the antilog 10%5Ex of both sides
%28Po%29%2F%289.8%29 = 19.952
Po = 9.8 * 19.952
Po = 195.5 watts, output power

Check on a calc
10%2Alog%28%28195.5%2F9.8%29%29 = 12.999 ~ 13 db
