(l) In a discrete simulation, a variable that is an output of one period and that predicts what the output of some future period will be. (2) In an analog simulation, a variable that is a function of an output variable and that is used as input to the simulation to provide advanced time response or feedback. [DIS; IEEE]
(1) Imfaniso eyodwa, engaguquguqukiyo esisiphumo sexesha elithile kwaye ethelekelela ukuba lizakuba yintoni ikamva lesiphumo. (2) Kwimfaniso efana yodwa, utshintsho olungumsebenzi wokutshintsha kwesiphumo kwaye lusetyenziswa nje ngegalelo lwemfaniso ukunikezela ngempendulo eyongezelelweyo. [DIS; IEEE]
