White noise

Post by Nimlidor » 8.10.2006 21:08

Na netu sem našla to difinicijo:

White noise is a type of noise that is produced by combining sounds of all different frequencies together. The adjective "white" is used to describe this type of noise because of the way white light works. White light is light that is made up of all of the different colors (frequencies) of light combined together. In the same way, white noise is a combination of all of the different frequencies of sound.

Zanima me, če je "beli hrup" sploh domena znanosti in ga je možno dobiti ali pa je to samo izraz za nevzdržen hurp?

Ma čist si zgrešu.. :lol:
Kot prvo 'white noise' se ne prevede v 'beli hrup' temveč kot 'beli šum'.
Beli šum je oblika (točnejše definicija) motnje merjenega signala.
Beli šum je v znanosti poznan kot simetrična v spektralnem spektru dokaj enakomerno po času porazporejena motnja.
Še drugče: beli šum je meja območja razpoznavnosti/uporabnosti merjenega signala na skrajnem območju zaznavnosti merilne naprave. Naprava sicer lahko še meri, vendar pa so meritve neuporabne.8)
Termin 'beli šum' ni nujno povezn izključno z zvokom, temveč velja za valovanje na splošno!
Lahko noč..
