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)
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 ...
Decibel (dB) definition, how to convert, calculator and dB to ratio table. Decibel (dB) definition Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain. Decibel is used to indicate the level of acoustic waves and electronic signals. ...
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
If the signal power at a receiver is-110 dBmand the noise power is-150 dBm, the Signal-to-Noise ratio is the difference between the two dBm values: SNR = -110-(-150) = 40 dB Another example of this is when converting fromEIRP to ERPorERP to EIRPusing the numerical value of the ...
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...
This tool converts linear power and voltage ratios to dB and vice versa. VSWR Converter: This tool converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss and mismatch loss. ...
dBm is a power ratio relative to 1mW, dBu and dBV are voltage ratios, relative to 0.775V and 1V, respectively. To use this calculator enter your application data in the section provided, then enter the quantity you wish to convert in the appropriate form element. Tabbing to another field,...
Derived from the Bel (in honor of Alexander Graham Bell) – the Decibel corresponds to 1/10 of a Bel . The unit – one Bel at its origin – represents the power ratio of 10 to 1 between the intensity (power) of two sounds.
The dBCalculator software comprises five independent calculation tools: dBm Calculator: This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt. Voltage Calculator: This tools helps to add and subtract correlated and uncorrelated voltage levels. ...
