10 * log P out / P in =32Originally posted by tjjam2003@Apr 18 2006, 07:31 PM
An amplifier has a decibel power gain of 32dB. What is the ordinary power gain?
Now if dB= 10 log P out / P in
How do I rewrite thew formula to find the ANSWER of 1584.89???

antilog(3.2) = 10 ^ 3.2

On the off chance that you might not know what an antilog is. It is the same raising 10, the base of common logarithms, to the power of the argument. In symbols:
If you already knew this, then I apologize for being presumptuous.Rich (BB code):antilog(3.2) = 10 ^ 3.2

10 * log P out / P in =32
So log P out / P in = 3.2
Get antilog of 3.2. On my calculator that's
Shift > Log > 3.2 = 1584.893192
