Decibels is the Power Gain of Ampliers and Filters

WebWe can double check our answer of 40dB by multiplying the individual gains of each stage in the usual way as follows: A power gain of 20dB in decibels is equal to a gain of 100, as 10 (20/10) = 100. So: (or 10,000 times greater) Converting this back to a decibel value gives: dB Gain = 10log 10 [10,000] = 40dB.
