decibel calculation

decibel calculation

(OP)
Hello All
I have this code

Private Sub cmdCalcPowerDbGainLoss_Click()
Dim PowerGainRatio As Double
PowerGainRatio = Me.tboxOutputPower / Me.tboxInputPower

Me.tboxDbGainLoss = Log(PowerGainRatio) * 0.43429
Me.tboxDbGainLoss = Me.tboxDbGainLoss * 10

Me.tboxVoltageDbGainLoss = Log(PowerGainRatio) * 0.43429
Me.tboxVoltageDbGainLoss = Me.tboxVoltageDbGainLoss * 10 * 2

End Sub

It takes a given input power/voltage and and an output power/voltage and calculates
decibel gain/loss (accurately I think)

I would also like to enter an input voltage and a Decibel gain/loss and calculate the output voltage
but I can't figure out the equation to do it, math skills not so great

thanks
