# Ratio of the amplitude from the decibel

## Calculates the input and output power and voltage ratios from the decibel (gain)

Gain G
 dB

Voltage ratio Vo/Vi
Power ratio Po/Pi
 $\normal \vspace{5}\\\hspace{10}Voltage:\hspace{10} {\large\frac{Vo}{Vi}}=10^{\normal\frac{G}{10}}\\\hspace{10}Power:\hspace{20} {\large\frac{Po}{Pi}}=10^{\normal\frac{G}{20}}\\$
