Thus, 0 dBrn = -90 dBm. Use of 144 line , 144-receiver, or C-message weighting , or flat weighting , can be indicated in parentheses . With C-message weighting, a one- milliwatt , 1000 Hz tone will read +90 dBrn, but the same power as white noise , randomly distributed over a 3 kHz band will read approximately +88.5 dBrn, because of the ...
Many different levels with a number of different weightings are in current use, and care must be taken to ensure that the proper parameters are stated. Specific ones include: dBa , dBa(F1A), dBa(HA1), dBa0, dBm , dBm(psoph), dBm0 , dBrn , dBrnC , dBrnC0, dBrn(f 1 -f 2 ), dBrn(144-line), dBx.
Examples of electrical noise-level measurement units are dBu, dBm0, dBrn, dBrnC, and dBrn(f 1 − f 2), dBrn(144-line). Noise may also be characterized by its probability distribution and noise spectral density N 0 (f) in watts per hertz. A noise signal is typically considered as a linear addition to a useful information signal.
