Abstract: Method and apparatus for selecting data wherein the acceptability of the data is a function of a measurable quality, such as duration, of a specific event relative to the current average, or other statistical threshold, of such quality of a number of events. The magnitude of event characteristic is measured and provided as a signal. Deviations from the threshold are provided to an up-down counter in which the threshold is stored and, accordingly, updated. If the event magnitude, as registered in an up-counter, exceeds the updated threshold stored in the up-down counter, a digital comparator indicates this and up counts the up-down counter to the extent the event exceeds the threshold. If the event magnitude is less than the stored threshold, the up-down counter is down-counted an amount corresponding to the difference between the event magnitude and the stored threshold. A currently updated threshold is thus maintained in the up-down counter.
