Basically i am searching for the Watts to dB Conversion formula or relation Thanks, Deepak Hi, Deepak, The dB units always depend of a reference. In power units, there are dBW and dBm units to refer the gain relationship between a 1W or 1mW. dBW means dB relative to 1 watt, s...
Firstconvert dBm to Watt PdBm1= 30 dBm = 1 Watt PdBm2= 10 dBm = 0.01 Watt The ratio between the two is 1/0.01 = 100. On the log scale it works out to: 10*Log10(100) = 20 dB Let’s see if this works for negative values of dBm. ...
of1millwatt.Theequationis:dBm=10lg(P/1mW). 1)ifthe transmit power P is 1mW, it is converted to dBm and then 0dBm; 2) for any power (such as 20W), the value after conversion is 10lg (20W/1mW) = 10lg20000 = 43dBm in dBm units. ...
We don't use the dBm in audio engineering. That belongs to power, we don't need here. If you really needdBmwith "m = 1 milliwatt or one thousandth (10−3) of a watt", go to: The dBm calculator and power matching or impedance matching ...
power quantity, e.g. watts) in the formula. The barchanges plus and minus, when dB is chosen. It makes the reciprocal, when factor (ratio) is chosen. The formulas for voltage and power and the level calculation To use the calculator, simply enter a value. ...
In summary, dB is usually used to indicate the magnitude of the circuit loss and gain. DBm DBm is a representation of the absolute value of power. It is based on a decibel (decibel) field that is based on a decibel of 1 millwatt. The equation is: dBm = 10lg (P/1mW). 1) if ...
dBW or dB(W) (decibel watt, power ratio) — absolute power in decibels relative to 1 W. For example, the transmitter power level is +40 dBW or 10 kW. Electric Current (absolute) dBμA or dB(μA) (decibel microampere, amplitude ratio) — absolute current in decibels relative to 1 ...
