Specialty Definition: Noise level

(From Wikipedia, the free Encyclopedia)

In telecommunication, noise level is the noise power, usually relative to a reference.

Note: Noise level is usually measured in dB for relative power or picowatts for absolute power. A suffix is added to denote a particular reference base or specific qualities of the measurement. Examples of noise-level measurement units are dBa, dBa(F1A), dBa(HA1), dBa0, dBm, dBm(psoph), dBm0, dBm0P, dBrn, dBrnC, dBrn(f ₁ - f₂), dBrn(144-line), pW, pWp, and pWp0.
