When applied to electron beam devices and devices employing distributed nonlinear media, the variable parameter is equivalent to a reactance in the sense that it is associated with energy storage rather than eiiergy dissipative properties of the beam or medium. The qualifier, reactance, is more frequently applied to circuits in which the variable element is an easily identified lumped reactance. The qualifier, parametric, is more frequently applied to electron beam and distributed parameter devices, but can include the variable reactance devices as well. Thus in any of the following definitions, reactance may be used in place of parametric. These definitions are intended to exclude devices which operate by virtue of variable resistance or negative resistance. 517 $aIEEE No 254-1963 606 $aParametric devices 606 $aTerminology 606 $aStandards, Engineering 615 0$aParametric devices. 615 0$aTerminology. 615 0$aStandards, Engineering. 676 $a621.381533 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996280658503316 996 $aIEEE Number 254-1963$93647273 997 $aUNISA LEADER 02229oas 2200781 a 450 001 9910143817503321 005 20251105213014.0 011 $a1950-6821 035 $a(DE-599)ZDB2241268-2 035 $a(OCoLC)173314810 035 $a(CONSER) 2007263128 035 $a(CKB)991042723471290 035 $a(EXLCZ)99991042723471290 100 $a20070926a20009999 sy 101 0 $afre 135 $aurbn||||||abp 135 $aurbn||||||ada 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aMathe?matiques & sciences humaines 210 $aParis $cCentre d'analyse et de mathe?matique sociales, Ecole des hautes e?tudes en sciences sociales$d[2000]- 215 $a1 online resource 300 $aRefereed/Peer-reviewed 311 08$a0987-6936 517 3 $aMathematics & social sciences 517 1 $aMathe?matiques et sciences humaines 517 1 $aMSH 517 1 $aMSS 517 1 $aMathematics and social sciences 531 0 $aMath. sci. hum 606 $aProbabilities$vPeriodicals 606 $aMathematical statistics$vPeriodicals 606 $aProbabilite?s$vPe?riodiques 606 $aStatistique mathe?matique$vPe?riodiques 606 $aMathematical statistics$2fast$3(OCoLC)fst01012127 606 $aProbabilities$2fast$3(OCoLC)fst01077737 608 $aPeriodicals.$2fast 615 0$aProbabilities 615 0$aMathematical statistics 615 6$aProbabilite?s 615 6$aStatistique mathe?matique 615 7$aMathematical statistics. 615 7$aProbabilities. 676 $a519.2/05 712 02$aE?cole des hautes e?tudes en sciences sociales.$bCentre d'analyse et de mathe?matique sociales. 801 0$bTXA 801 1$bTXA 801 2$bTXA 801 2$bMYG 801 2$bOCLCE 801 2$bOCLCQ 801 2$bOCLCF 801 2$bCUS 801 2$bNUI 801 2$bTXJ 801 2$bFIE 801 2$bI8H 801 2$bCUS 801 2$bOCLCQ 801 2$bVT2 801 2$bOCLCQ 801 2$bOCLCO 801 2$bOCLCQ 906 $aJOURNAL 912 $a9910143817503321 996 $aMathématiques & sciences humaines$91939538 997 $aUNINA
