The expressions provide useful insight into the behaviour of the CRBs with the frequency separation and the damping factors of the cisoids.eninfo:eu-repo/semantics/closedAccessEngineeringParameter estimationDamped cisoidsCramér-Rao boundsClosely spaced signalsSpurious signal noiseParameter estimationNatural frequenciesData structuresDampingSignal processingNoiseParametersArticle0002410935000262-s2.0-33748335722338833928611Engineering, electrical & electronicSubspace Identification; Modal Analysis; Cable-Stayed Bridge
