Calculating the Multiplier from Decibels
Calculate the output-to-input ratio (multiplier) for power or voltage from decibels (gain).
| Voltage Ratio Vo/Vi | Multiplier |
| Power Ratio Po/Pi | Multiplier |
Even with the same decibel value, the output-to-input ratio differs between power and voltage.
| \(\normalsize \\ \hspace{10px}Voltage:\hspace{10px} {\large\frac{Vo}{Vi}}=10^{\normalsize\frac{G}{20}}\\ \hspace{10px}Power:\hspace{20px} {\large\frac{Po}{Pi}}=10^{\normalsize\frac{G}{10}}\\\) |
