10log x = 19.78
日志x = 1.978
x = 10 ^ 1.978
10log x = 19.78
日志x = 1.978
x = 10 ^ 1.978

或aproximated方式：
0dBW = 1瓦
10瓦分贝= 10瓦
20瓦分贝= 100瓦
19.78略低于20因此
，答案是19.78瓦分贝= 20瓦分贝- 0.22分贝，
-0.22分贝= 0.9506，所以20瓦分贝- 0.22 =
100x0.9506 = 95.06糯糯
0dBW = 1瓦
10瓦分贝= 10瓦
20瓦分贝= 100瓦
19.78略低于20因此
，答案是19.78瓦分贝= 20瓦分贝- 0.22分贝，
-0.22分贝= 0.9506，所以20瓦分贝- 0.22 =
100x0.9506 = 95.06糯糯

典型的计算公式为：
分贝= 10log（规划）
在这里你可以在瓦功率
分贝= 10log（规划）
在这里你可以在瓦功率
