dBc dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.
Noise Density Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.
Spurious Signals Spurious signals are undesired signals. They can be considered in two classes. They can be stationary; their frequency and amplitude do not change significantly, or non-stationary, where the frequency and/or amplitude change significantly over short time periods.
