The following Calculator application will convert Voltage Gains or Power Gains into Decibels. We know that Decibels provide a logarithmic measure that simplifies comparisons of ratios and levels, which is especially useful when dealing with large ranges of values like in electronics and audio system applications. Here we have used result formula as “dB = 20log10(V1/V2) = 10log10(P1/P2)“. You can enter any one of the three values in the input field and this calculator will give the output result of the other two.
Decibel (dB) Gain Calculator
Here is the method used to calculate values.
When the Voltage Gain (Vout/Vin): is only given as input.
When the Power Gain (Pout/Pin): is only given as input.
When the Decibels (dB): is only given as input.
In some places Voltage Gain is denoted as AV and the Power Gain is denoted as AP.
