6 dB is a "good" attenuation.
db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02
In a 3dB coupler, the "dB" stands for decibels, which is a unit to measure the attenuation or gain of a signal. The 3dB value indicates that the signal power is divided equally among the output ports, resulting in a 3dB loss compared to the input signal power.
To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
Sure, after all it is a logarithmic scale.
To convert from dB (decibels) to mW (milliwatts), you can use the formula: mW = 10^(dB/10). Simply take the dB value and divide it by 10, then raise 10 to that power to get the mW value. For example, if you have 20 dB, the calculation would be mW = 10^(20/10) = 100 mW.

100 percent means full voltage or 0 dB.When 75 percent of the voltage is lost you still have 25 percent of the voltage.25 percent means damped to (-)12 dB.
dB per kilometerNote: Depends on frequency of the radio signal, and on the rate at which rain is falling.
A: Clipping only occurs if the input surpasses a threshold like the Vbe of a transistor. The 20 Db is really a change3 in voltage of a 100 that is not a small change
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.

Send me the reference value (0 dB) for frequency.
