Deutsche Version

The reinforcement and also the amplification factor are called simply "gain" and its increase value with
amplification is positively designated. Loss or decrease is the damping factor, "negative gain" or also "attenuation".
Field and power gain factors and loss factors are ratios.

Conversion

• Linear field quantity: e. g. Voltage Gain and Loss •

Enter the value for V in and V out and press the "=" key.

Level L_field = 20 × log₁₀ (	V out		) dB gain
	--------	---------------
	V in
"V in" is the reference

Level L_power = 10 × log₁₀ (	P out		) dB gain
	--------	---------------
	P in
"P in" is the reference

Voltage V: Volt	↔	Voltage level L_U: dBV
$V = V_0 \cdot 10^\frac{L_V}{20} \ \mbox{volts}$		$L_V = 20\, \log_{10}\left(\frac{V}{V_0}\right) \ \mbox{dBV}$
Reference voltage V₀ = 1 Volt (0 dBV)

Electric power P: Watt	↔	Electric Power level L_P dB

Reference power P₀ = 1 W (0 dB)
