REVISION SUMMARY Add decibel power units (dBW and mulitples) Decibel power units are widely used in the fields of signal trasnmission and radiofrequency. This patch adds decibel units to the Power category (dBm, dbW, dBµW and dBk). The decibel calculation might be also interesting to other categories such as voltage or pressure (acoustics) TEST PLAN - Check the units of the power category on krunner - The reference unit: 1W = 0dBW = 30dBm = 60dBµW = -30dBk - The decibel is a logarithmic scale so multiplying on natural units implies addition in decibel units: 10W = 10dBW = 40dBm = 70dBµW = -20dBk REPOSITORY R292 KUnitConversion BRANCH log_power_units REVISION DETAIL https://phabricator.kde.org/D23103 AFFECTED FILES src/power.cpp src/unit.h To: iasensio Cc: kde-frameworks-devel, LeGast00n, michaelh, ngraham, bruns
