Nettetany value of dB. Raise the value 1.26 to the decibel value. For example, to find the power ratio corresponding to a decibel value of 12 dB, enter 1.26 into the calculator, press … NettetSo to add two decibels, just convert them to powers first, add the powers and then convert back. For 90 dB, the corresponding P = 10 9. Adding two 10 9 gives 2 × 10 9. Then take the log and multiply by 10 to get 93 dB. What you're missing is converting the power back to d B.

To wit: N dB = 10 * log10 (P1/P2) All gains greater than 1 are therefore expressed as positive decibels (&gt;0), and gains of less than 1 are expressed as negative decibels (&lt;0).

NettetThe decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B).It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale.Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.26) or root-power ratio of 10 1 ⁄ 20 (approximately 1.12)..
