Circuit noise level: At any point in a transmission system
, the ratio of the circuit
noise at that point to an arbitrary level chosen as a reference.
Note: The circuit noise level is usually expressed in dBrn0, signifying the reading of a circuit noise meter, or in dBa0, signifying circuit noise meter reading adjusted to represent an interfering effect under specified conditions.
