The measure of brightness in video images. Black is usually defined as 7.5 IRE; white as 100 IRE, with all other brightness levels falling between these two values.
Acronym for the North American 'Institute of Radio Engineers'. Also refers to the measurement units introduced by this organization. As defined by ANSI/IEEE standard 205, ' IRE unit s are a linear scale for measuring the relative amplitudes of the component.
A unit of measurement of the video waveform scale for the measurement of video levels, originally established by the Institute of Radio Engineers. The scale is divided into 140 IRE units, 100 above the blanking reference line and 40 below it.
A relative unit of measure (named for the Institute of Radio Engineers). One IRE equals 1/140th of the composite video signal's peak-to-peak voltage.
Integrated Research Experiment ( IRE) is conceived as an intermediate-scale device, combining a multiple-beam injector, eletrostatic and magetic transport lattices, acceleration, longitudinal confinement, steering, compression, final focusing, and chamber transport. The experiment would provide the science basis for designing a larger Experimental Test Facility ( ETF).
Institute of Radio Engineers. IRE units measure relative amplitudes of television signal components on a linear scale. One of the units of measure in a waveform monitor is IRE's.
Institute of Radio Engineers. IRE units are a linear scale for measuring the relative amplitudes of the components of a television signal. The scale on a waveform monitor is measured in IREs.
Institute of Radio Engineers. Now called IEEE, the Institute of Electrical and Electronic Engineers. See " IEEE."
Acronym for Institute of Radio Engineers. The Institute of Radio Engineers was founded in 1912 -- the second organization that would eventually merge to found the IEEE in 1963. IRE units are a linear scale for measuring the relative amplitude of the component of a television signal with a zero reference at the blanking level.
Independent Review Entity. Groups of health care professionals who are hired by the Federal Government to review medical necessity, appropriateness and quality of medical care and services provided to Medicare beneficiaries. Upon request, the IRE also reviews hospital discharges for appropriateness and quality-of-care complaints.
Institute of Radio Engineers. Units of measurement dividing the area from the bottom of sync to peak white level into 140 equal units. 140 IRE equals 1Vpp. The range of active video is 100 IRE.
An arbitrary unit of measurement equal to 1/100 of the excursion from blanking to reference white level. In NTSC systems, 100 IRE equals 714mV and 1-volt p-p equals 140 IRE.
An IRE is a unit used in the measurement of composite video signals. Its name is derived from the initials of the Institute of Radio Engineers.
