How many dB of attenuation translates into 50 percent of the voltage being lost to attenuation?

db=20log(V1/V2) or 10log(P1/P2) Example: db=20log (100/50) db=20log(2) db=20*.3010 db=6.02

What is db in 3db coupler?

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.


How many dB attenuation translates into 75 percent of voltage being lost to attenuation?

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.


In what units is the rain attenuation of radio signal expressed?

dB per kilometerNote: Depends on frequency of the radio signal, and on the rate at which rain is falling.


Why there is a clipping in the signal output when you change the attenuation from 20db to 0 db in function generator?

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


How do you converts ohms to dB?

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.


How do you convert dB to DBi?

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.


Send me the conversion for Kilo HZ to DB?

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


Is it possible to have a dB value less than 0dB?

Sure, after all it is a logarithmic scale.


How do you convert db to mw?

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.
