Nan dB, dbm kalkil, peye atansyon sou konsèp de baz yo. Egzanp, te di byen bonè 0dBw = 10log1W = 10log1000mw = 30dBm; Kòm yon lòt egzanp, ak yon dbm pa yon lòt dbm, rezilta a jwenn se dB. Tankou: 30dBm - 0dBm = 30dB.

In dB, dBm calculation, pay attention to basic concepts. Example, said earlier 0dBw = 10log1W = 10log1000mw = 30dBm; As another example, with a dBm by another dBm, the obtained result is dB. Such as: 30dBm - 0dBm = 30dB.
