• Fourth, the RF common sense science:
  dB is a pure count of unit:
  For power, dB = 10 * lg (A / B).
  For voltage or current, dB = 20 * lg (A / B).
  dBm is defined miliwatt (mW). 0 dBm = 1mw;
  dBw defined watt. 0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm.
  dB power units are always defined by default, to 10lg for scoring. Of course, some cases may signal strength (Amplitude) to describe the work and power, this time with 20lg for scoring. Whether in the field or control signal processing field like this. For example, sometimes you can see the expression dBmV.
