Determine the power gain, G, in decibels, for an amplifer with output P0 of 20 watts and an input Pi of 1.5 watts. round to five decimal places
G=log(Po/Pi)^10
:
I think the formula for decibel gain (or loss) is: db = 10*log()
:
db = 10 log()
find the log of 20/1.5
db = 10 * 1.124939
db = 11.24939 db gain
