Dans les schémas ci-dessous, calculer le gain ou la puissance, 2) -6 dB correspond à un rapport de 1/4 ; P = 20 / 4 = 5 W. Le triangle représente un circuit dont le gain est donné en dB. Since a decibel is 1/10th of a bel, you'll always have 10 times as many decibels as compared to Bels. The unit they invented was initially called the Transmission Unit (TU) but was quickly renamed to the decibel (dB), in honor of telecommunications pioneer Alexander Graham Bell. The official unit is the Bel, which is an order of magnitude or a power of ten, a single unit in the logarithmic number system. To convert from decibels back to a number ratio, a calculator is generally used, although it’s still a straightforward process. Si le gain exprime un rapport de tensions, le gain est doublé par rapport aux mêmes valeurs exprimées en watts. The max-peak history is automatically reset as soon an as audio parameter changes.
