The leading measure decibel (dB) is used to compare the voltage.Looking at rakan expands in units of decibel output, or political pressure, divided by the voltage of the Eo input or Ei multiplied by 20 Log base 10.
Bringing measured in decibels (dB) compared to the pressure for expansion ratio in decibels of the output voltage or the input voltage Eo dividing or multiplying by 20 Log Ei base 10.
Application of DB (dB) for comparing the voltage finding rate in units of pressure on expand DB output or Eo divided by the input voltage. Ei multiplied by 20 Log 10 base.
