IRE (unit)

IRE stands for "Institute of Radio Engineers," and it is a unit of measurement used to indicate the level of video signals. Specifically, the IRE unit quantifies the amplitude of video signals in terms of their voltage relative to a reference level. In the context of video signals, the IRE scale ranges from 0 to 100, where: - 0 IRE represents the "black" level (the darkest part of the image).
