The observation that the fine structure of turbulence is both spatially and temporally intermittent has led to a sizeable amount of theoretical and experimental work. It is unfortunate that the data from these several sources are mutually inconsistent in many qualitative and quantitative respects. In the course of assessing various experimental procedures, it became clear that some of the properties attributed to fine-scale turbulence are also shared by other band-pass filtered random signals. To put this assessment on firmer grounds, the author examined a simple analytical tool with a fairly wide applicability to a study of random signals passed through narrow-band filters. Corroborating measurements were also made. All measurements were made in flat-plate boundary layers in blower-type subsonic wind tunnels using standard hot-wire equipment.
