25dB equal to how many watts?
That depends on you. If you want, you can say 1 watt should be 0 dB.
How many watts does an EPIRB transmit?
5 watts +/- 3 dB
How many amps are a 100 watts?
Given: Power P = 100 W. Reference power Po = 10^−3 W = 1 mW. Reference power level LPo = 0 dB. Get power P when entering power level LP: P = Po×10^(LI/10) W = 10^−3×10^(LP/10) W. Get power level LI in dB when entering power P in W. LP = 10×log (P / Po) dB = 10×log (P / 10^−3) = 50 dB. The reference power may be different, then the power level will be different.
How many watts of power are represented by 0 dbm?
A decibel is a measure of relative power, to compare one power level with another. 'dBm' means dB relative to 1 milliwatt and is a common unit of power in communications systms, and 0 dBm is the same thing as 1 milliwatt.
How many decibel is equal to one Hz?
Impossible question, like asking "One Apple is equal to how many oranges" Simply set : Decibels it the unit of volume, how loud things go hertz is how fast things change, the frequency (number of changes per second). When you talk about music, different frequencies can have a different volume. You can even measure the volume in frequency ranges - look up : paragraphic equalizer for the principle. Geert Fieuw Beyond The Labyrinth ----------------------------------------------------------------------- +db= 10*log(p2/p1) +db= 10*log(2watts/1watt) +db= 10*log(2) +db= 10*.30103 +3.0103= 10*log(2watts/1watt) so double the power you gain 3db's so double the sound you gain 30dbs and p2 is 1000 times p1 +db= 10*log(p2/p1) +db= 10*log(1000watts/1watt) +db= 10*log(1000) +30= 10*3 test signal say 60 Hz

How many watts does an EPIRB transmit?
5 watts +/- 3 dB
If transmitter power is increased from 200 Watts to 400 Watts how do you convert to Db form?
Decibels (db) is relative power, log base 2, times 3. Increasing power from 200 watts to 400 watts is doubling power, so the decibel change is +3 db.800 watts would be +6 db, 1600 watts would be +9 db, 100 watts would be -3 db, 50 watts would be -6 db, and so on.
How many watts is 98db?
It depends on the reference. If the reference electric power is P0 = 1 W (0 dB) then 98 dB equals 6309573444.8 Watts.
How do you convert 13.936 dB to watts?
In power wattage increases by two times for every three DBs of increase. A starting point is needed to do this calculation. The equation you're looking for is 10*log |P| = P in dB for example, 0 dB = 1 watt 10 dB = 10 watts for 13.936dB, 10^1.3936 = 24.75 watts.
If a 13 dB gain antenna has 2 watts of power at the input what is the effective radiated power?
40 watts
Why is dB IL equal to dB SPL?
IL is not equal to SPL. Actually SPL = IL + 0.16dB.
Convert 100W into decibels?
Given P = 100 watts. Reference sound intensity Po = 10^−12 W. Reference sound intensity level LPo = 0 dB. Get power level LP in dB when entering sound power P in watts. Power level LP = 10×log (P / Po) dB = 10×log (100 / 10^−12) = 140 decibels (dB).
Calculate the power out put of an amplifier that has an input of 15 μw and a gain of 25dB?
If you want to work in watts, convert 25dB to a scalling factor: 3dB = 2 x input 10dB = 10 x input 20dB = 100 x input ...25dB = 10 ^ (25/10) = 316.2 x input So the output is 15 micro Watts x 316.2 = (4700)/(10^6) = 4.7 milli watts If you want to work in dB, then convert 15 micro watts to dB: 10 * log |P| = dB = 10*log |15 x 10^6| = -48.2dB ***When you have very small (ie negative) dB, it is often referred to in dBm, or 1/1000 of dB ( 30 dBm = 0 dB) so the output is -18.2dBm + 25 = 6.8dBm, or -23.2dB
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
What is the loudness in sones for 4000 Hz at 90 dB?
90 decibel is 32 sones.
One decibel is equal to in bel?
One decibel (dB) is equal to one tenth of a bel (B).
