NOTE: The IRE (Institute of Radio Engineers – now IEEE) scale is used for defining the relative voltage levels of the sync, white, black, and blank
levels in a monitor circuit. The reference white level is set at 100 IRE units. The blanking level is set at φ IRE units. One IRE unit is equivalent
to 1/100 of the difference between the reference white level and the blanking level.
