What is the formula to convert voltage levels to decibels?
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"
How do you convert db to number using log?
Decibels (db) is 3 times the log based 2 of the difference in power. To convert from db to power, divide by 3 and compute the inverse log based 2. For example, +6db is 26/3 or 22 or 4 times the power, and -9db is 2-9/3 or 2-3 or one eighth the power. If you are attempting to compute voltage, remember that db is power difference, so you need to take the square root of the difference, because power is voltage times current, and current is voltage divided by resistance, so power is voltage squared divided by resistance.
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
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.
The db gain is -3.5 what is the ratio of vout to vin?
Gain in decibels is a logarithmic base 2 scale with a multiplier of 3, so 3 db is twice the power, 6 db is four times, etc. Gain of -3.5 db means a power loss of 21.17, or a ratio of about -2.25. Note, however, that this is power, not voltage. Since power is voltage times amperes, and since amperes is voltage divided by resistance, in order to achieve a power loss of 2.25, the voltage must change by the square root of that, so the voltage changed by -1.5.

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
How do you convert signals from voltage levels to their corresponding decibel equivalents and from decibel levels to their corresponding voltage or current levels?
convert signal gains or losses to comparative decible reading.
Find the output voltage of an amp whose input voltage is 0.05 volt and db gain is 35 db?
db gain is defined as power gain, not voltage gain. Please restate you question in terms of power, or provide details of input and output impedance.
How do you convert dB to liters?
If I understand the question, it isn't possible to convert dB (a unit of sound energy) to litres (a unit of volume).
If the transmit voltage is increased by a factor of 100 how many dB has the power been increased?
2 db's.
What is the Formula to covert voltage level to decibel?
You mean the conversion from voltage V to voltage level LV. Voltage level LV = 20 * log V 117 volts equals 41.36 dB. The reference voltage 1 volt means 0 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.
If gain is 10 db what is the ratio of voltages?
10 dB gain means a voltage ratio of 3.16227766 to 1.
