Calculation method
Calculation method
Power ratio (dB)
10 × log10(a ÷ b)
Symbols and units
- a
- Output power
- b
- Reference power
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
log10(x) is the logarithm to base 10.
Assumptions & limits
Assumptions & limits
- For power use 10 log10 of the ratio. Amplitude ratios use a different formula under equal impedance.
