Reference noise
In telecommunication, reference noise is the magnitude of circuit noise chosen as a reference for measurement.
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, dBa, dBa0, dBm, dBm, dBm0, dBrn, dBrnC, dBrnC0, dBrn, dBrn, dBx.
