Noise voltage

from Wikipedia, the free encyclopedia

A noise voltage is usually expressed as a summary noise level in  dB that is generated by system-related electrical and acoustic sources of interference in a transmission system for acoustic signals.

The measurement of the noise power is made via a weighting filter that the frequency dependence of the ear sensitivity is adjusted (see curves of equal volume level ) and, depending on the transmission system (such as radio or telephone differs)

To form the noise voltage interval , the noise voltage to be useful voltage ( wanted signal ) is set in the transmission system ratio.
