₢킹Bm은1兆瓦의전력을기준으로비율로간주될수있는전력(전력값/ 1 mw)로계산되는값입니다。여기서우리는" 1벤치마크”와“2원칙”으로요약된W로계산dBm의방법을소개합니다:

1大:

30dBm=1W

2;

1:

+ 3dB→2 * * * * * * *-3dB, 1/2，超大型，超大型，超大型

예:

: 33dBm=30d Bm+3dBm=1W×2=2W

27dBm=30d, Bm-3dBm=1W×1/2=0.5₢

2:

+ 10dBm + 10dBm-10 d Bm 1/10에의의하여힘

예:

40dBm=30d、40dBm= 1W × 10 = 10W

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

위는단순히기록될수있습니다:30는벤치마크,1 w와동일하,교환은어렵지않습니다,가장간단한항구조사。3个30:10,10个30:10;2 * * * 3 * * * 10 * * 10 * *

거의모든정수에대한dBm는" 1벤치마크”와“2원칙”으로W로변환할수있습니다。

44 dbm = ?₢킹

: 40dBm=30dBm+10d

= 1 w×10×10×1/2×1/2 = 25 w

[qh]

32 dbm = ?₢킹

32dBm=30d, Bm+3dBm+3dBm+3dBm+3dBm +3dBm- 10dbm

= 1 w×2×2×2×0.1 = 1.6 w

■■■■

+ 1dBm + 2d Bm

1dBm=+10d， * * * * * * * * * * * * * * * * * * * *

₢10×1/2×1/2×1/2

= X×1.25의

+2dBm=-10d * Bm+3dBm+3dBm+3dBm+3dB m/ hz

= X 0.1××2×2×2 = X×1.6 w

계산에서,때로는위의규칙에따라1 dbm및2 dbm로변환할수있습니다,급속한입속도의목적을달성하기위해,즉:

-1dBm=-10d * * Bm+3dBm+3dBm+3d * * * * m/ * *

= X 0.1××2×2

= X×0.8의

-2dBm=-3dBm+ 1dbm / hz

[qh]: x×1/2×1.25

= X×0.625의

[qh]

50dBm=30dBm+10d: Bm+10dBm+1dB m/ k

= 1 w×10×10×1.25
