A noise figure is a scale of decibels.
hi as we know noise temperature relate to noise figure as ................. T = T0(NF-1) where T0 is referance figure and NF is noise figure NF = (S/N)in --------- (S/N)out S/N is signal to noise ratio
say, overall noise figure =f noise figure of stage1=f1 noise figure of stage2=f2 f=f1+(f2-1)/g1 f1,f2 are in linear scale(not in dB) g1=gain in stage1
Noise figure is one of those cases that is crucial, and that calls for experienced care about
To use a noise decibel meter, simply turn it on and place it in the area where you want to measure noise levels. The device will then give you a readout in decibels, indicating the intensity of the sound in that location. Take multiple readings to get an average level of noise present.
When you can not figure out why your car makes a strange noise, you take it to a mechanic.
When I woke suddenly, I was too woozy to figure out the noise that woke me.
You'd have to define "better", and also exactly what you're seeking - we don't know if you're trying to deal with squealing noise, grinding noise, etc. or you want your car to sound more tuned.
Noise is defined as 'unwanted sound'. It is a subjective definition. [The word originates from the Greek and is related to nausea.]A wave is a periodic oscillation between two datum points. Consider the wave generated when a pebble is cast into a pond.
Ever figure this out? Mine is doing the same
A groyid is a unique figure. It makes lots of noise. It also moves a lot.
insertion loss the loss that occur the insertion of a device in transmit ion line or fiber .
You did not define "squeaky" but if there is a shrill noise when you startup or accelerate under engine load then it could be your serpentine belts slipping. Take a look at the 3 belts and see if they are glazed (shiny). If so then it is best to replace them.
