Decibel (dB) Calculator Decibels are defined as ten times the log of a power ratio or twenty times the log of Voltage Ratio.dB = 20log10(V1/V2) = 10log10(P1/P2) Input Enter either Power Gain (P1/P2) or Voltage gain to calculate the Decibel (dB). Power Gain (P1/P2): OR ...
It makes the reciprocal, when factor (ratio) is chosen. The formulas for voltage and power and the level calculation To use the calculator, simply enter a value. The calculator works in both directions of the↔sign. VoltageV(audio)
Voltage Calculator: This tools helps to add and subtract correlated and uncorrelated voltage levels. Unit Converter: This tool calculates for an entry using a unit such as dBm, dBW, mW, W, mV, V, dBV, dBµV and dBu the corresponding values for all other units, for individual impedance ...
To use the calculator below, input a value into the field and hit the enter key. The result will appear below. You can choose different calculations from the drop down menu. dB to Power RatioPower Ratio to dB dB to Voltage RatioVoltage Ratio to dB
Converting number relations (ratio) to dB level ● number - factor - ratio - parameter ● Voltage ratio: Level L (dB) = 20 × log (value 2 / value 1) That are field quantities Power ratio: Level L (dB) = 10 × log (value 2 / value 1) That are energy quantities Output value...
