Decibel Calculation from Input and Output
Convert from input and output amplitudes to decibels (dB)
| Gain G | dB |
| Ratio Out/In | times |
The gain calculation formula differs depending on whether the input and output are power or voltage.
| \(\normalsize \\ Power\ gain:\ G_p=10 \log({\large\frac{Po}{Pi}})\\ Voltage\ gain:\ G_v=10 \log({\large\frac{Vo}{Vi}})^2=20 \log({\large\frac{Vo}{Vi}})\\\) |
