How much louder is 50db then 30db?
The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity The sound of 50 decibles will have 105 and 30 db will have only 103 w/m2 sec.It is clear that first one has greater intensity
Why does a coupler break in a washing machine?
A coupler in a washing machine can break due to wear and tear from regular use, overloading the machine with heavy loads, or jamming of the coupler with foreign objects such as clothing or debris. Additionally, a misalignment in the machine's components can put added stress on the coupler, leading to breakage.
What color is lighter db 701 or db 703?
DB701 is lighter (They are German Railway Colours - Deutsche Bahn = DB)
Why is compressed air bad for an antenna coupler?
Compressed air can introduce moisture and contaminants into the antenna coupler, potentially causing damage and reducing its efficiency. Additionally, the force of compressed air can be too strong and could potentially misalign components within the antenna coupler, affecting its performance.
A sound of 20 dB intensity is twice as loud as one of 10dB?
No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.
What is 3dB coupler?
50% Coupler :D
What do means by 3 dB?
3 dB is a change in power by a factor of 2. If it is plus, i.e. +3dB, power is doubled. If it is minus, i.e. -3dB, power is halved. 6 dB, then is a factor of four, or quarter; 6 dB is a factor of eight, or eighth, etc. The actual equation is 3 log2 (POWER OUT / POWER IN).
What do you mean by 3 dB cutoff frequency?
3db frequency is the frequency at which the value in the graph is reduced by 3db level It's also known as the half-power point.
What is the db loss in optical fiber?
If there is a 3db loss that means 50 percent of the light were lost.
What is db gain?
DB (decibels) gain is the log based 2 times 3 relative power change measured from input to output of a circuit. For instance, +3db is twice the power, +6db is four times, +9db is eight times. Similarly, -3db is half the power, -6db is quarter the power, and -9 db is eighth the power.Keep in mind that DB is relative power, not voltage, so if you are measuring voltage, then +3db is square root of 2 (1.414) times the voltage, etc.
How 3db dandwidth equals half power bandwidth?
"3 dB" is a nickname for "1/2 power". "1/2 power" in dB = 10 log(1/2) = 10 (-0.30103) = -3.01 dB
What is the output if the input is 1kw and gain of 3db?
3 db is double the power, so an input of 1 KW would yield an output of 2 KW for a 3 db gain.
Does a 24db directional coupler or a small 3db inline connector boost a catv signal?
They must be powered to boost the signal. If they are not powered they are "passive" and will consume some of the signal.
How do you calculate input power of system with amplifier of 6 dB with a filter loss of 9 dB and an output power of 200 mW?
+6db -9db = -3dbso 400 mW -3db = 200 mWDecibels simply add, and they are 3 times the log base 2 of the power change, i.e. 3db, 6db, 9db is 2, 4, 8 times, and -3db, -6db, -9db is 1/2, 1/4, 1/8 times.
Would a 3db difference between two speakers that handle the same wattage make the one with 3 extra db twice as loud?
no
Why 3dB is required in the frequency graph?
as upto 3db only the amplifier gives the linear output & after that it gives non linear so it is difficult to determine it's characteristics.also up to 3 db it's energy efficiency is 70.3%. ANSWER: It imply that the amplitude on the output is half.....................
What is the decibel a unit of?
Decibel is no real unit, it is a pseudo unit. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity. A change in voltage ratio by a factor of two is approximately a 6 dB change. A change in power ratio by a factor of two is approximately a 3dB change.
