To convert a power ratio to dB, the formula is 10 log Po/Pi. For example,
if you had an amplifier that took 2 watts input and provided 40 watts
output, that ratio is 40/2 = 20. The common logarithm (base 10) of 20 is
1.30..., and multiply that by 10 and you get 13.01 dB gain.
Likewise, if you ha
Power gain = 10log P-Out/P-In
