dB Voltage Ratios
This calculation will give you the voltage ratio, in decibels, between two signal voltages.
For example, you can calculate the gain needed
to raise the output level from 0.775 volts to 1.4 volts.
You can also use this to calculate how much attenuation you need, if for instance you have a 2.0 volt input level, and you have to attenuate it to 0.2 volts to prevent input overload.
Enter any two values and press "Calculate" for the
remaining value. Press "Reset" before performing each calculation.
This form requires a Microsoft Internet
Explorer 4.0+ browser.
Note: Fields should be reset before each new calculation.
