Question 316458
An amplifier has an input power of 5 mW.
 The output power is 100 mW. 
What is the decibel gain to the nearest decibel?
:
The decibel gain equation: db = 10*log{{{((p2)/(p1))}}}
:
In this problem p1 = 5 mw; p2 = 100 mw
:
db = 10*log{{{((100)/(5))}}}
:
db = 10*log(20)
:
db = 10*1.301
:
db = 13 db gain
