采用dB作为传输电平的计量单位, 可以使工程中的乘除运算变成简单的加减运算。
For example, use an input signal of 100 mW to power a speaker and get a 100 W signal at the output. The formula for gain in dB will be dB = 10log₁₀(100 W/0.1 W) = 10log₁₀(1000) = 30 dB. 🙋 Are you looking for a material to mute loud noises in your environmen...

mW or 0 dBm. So it is just a fancy way of describing dB relative to 1 mW and unless this term is defined when used, it causes much more confusion than clarity. Remember, the reason that we use short hand notations is to facilitate ...

dBm indicates dB referenced to 1.0 milliwatt. One milliwatt = zero dBm. Thus P1 in above dB equations becomes 1.0 mW consequently 10 dBm = 10 mW, 30 dBm = 1W… dBV : dBV indicates dB referenced to 1.0 V. One volt = zero dBV. Thus U1 in above dB equations becomes 1.0 V consequently...
The dBm is a logarithmic measure of power compared to 1 mW, that means it is power dependent. It can be converted to a voltage, if the load impedance is known. Typically the impedance (load) is 600 ohms. Equation: Level in dBm: LP = 10 × log (P / 0.001)...
