A generalized signal-to-noise ratio for detectors is defined and its relationship to quality of detection is investigated. Specific attention is given to log-likelihood ratio detectors. The question is discussed as to whether a Central Limit Theorem approximation for the output of the detector gives results which are close to those of the actual detector and is illustrated with examples.
