Berekenen van versterking (gain) en demping (loss)

Enter two values and press the desired calculate bar

For now, we deal only with 'voltage' amplification (gain) and damping (loss).

V₂ >V ₁ = amplification, dB value is positive and V ₂< V ₁ = damping, dB value is negative.
V₂ / V₁ means the ratio. The amplification or the damping in dB is:
L = 20 × log (voltage ratio V ₂ / V ₁) V ₁ is the reference.

3 dB ≡	1.414 fold the voltage	- 3 dB ≡	damping to the value 0.707
6 dB ≡	2 fold the voltage	- 6 dB ≡	damping to the value 0.5
10 dB ≡	3.162 fold the voltage	-10 dB ≡	damping to the value 0.316
20 dB ≡	10 fold the voltage	-20 dB ≡	damping to the value 0.1

Using voltage we get: Level in dB: L = 20 × log (voltage ratio)

+6 dB = two fold the voltage
+12 dB = four fold the voltage
+20 dB = ten fold the voltage
+40 dB = hundred fold the voltage

Using power we get: Level in dB: L = 10 × log (power ratio)

+3 dB = two fold the power
+6 dB = four fold the power
+10 dB = ten fold the power
+20 dB = hundred fold the power
