Lub tshuab hluav taws xob tsim hluav taws xob yog ib qho hluav taws xob hluav taws xob lossis ib qho siv hluav taws xob sib tw siv los tsim hluav taws xob sib plawv. Cov tshuab hluav taws xob muaj feem siv rau kev ua haujlwm nrog digital circuits, muaj feem cuam tshuam lub tshuab hluav taws xob feem ntau yog siv rau cov hluav taws xob analog.
Cov khoom siv hluav taws xob yooj yim lub tshuab hluav taws xob feem ntau tso cai tswj cov mem tes rov ua dua (zaus), lub plawv dhia dav, ncua nrog txoj kev cuam tshuam rau sab hauv lossis sab nraud txhais thiab cov qib siab thiab tsis tshua muaj siab ntawm cov mem tes. Ntau lub tshuab ua kom muaj cov mem tes tuaj yeem tso cai tswj kev nce lub sijhawm thiab lub sijhawm poob ntawm cov mem tes. Muaj lub tshuab hluav taws xob muaj rau cov tsim hluav taws xob tso tawm muaj cov dav dav (ntev) ib ntu los ntawm feeb rau qis dua 1 picosecond. Cov tshuab hluav taws xob feem ntau yog cov khoom siv hluav taws xob, nrog cov hluav taws xob tiag tam sim no muaj rau los ntawm ob peb lub chaw muag khoom xwb. Cov tshuab tsim hluav taws xob (pulse generators) tuaj yeem siv cov txuj ci digital, cov cuab yeej sib txuas, lossis ob hom kev ua ke los tsim cov pulses tawm. Piv txwv li, lub plawv dhia rov ua dua thiab lub sijhawm ua haujlwm yuav raug tswj hwm digitally tab sis cov mem tes amplitude thiab sawv thiab lub sijhawm poob yuav raug txiav txim los ntawm analog hluav taws xob hauv cov zis theem ntawm lub tshuab hluav taws xob. Nrog kev kho kom haum, cov tshuab tsim hluav taws xob tseem tuaj yeem tsim tau 50% lub luag haujlwm voj voog square yoj. Lub tshuab hluav taws xob muaj feem ntau-ib-channel muab ib qho zaus, qeeb, qhov dav thiab tsim tawm.
Pulses ces tuaj yeem raug txhaj rau hauv lub twj tso rau hauv kev sim thiab siv los ntawm kev txhawb zog lossis lub teeb liab moos lossis kev tshuaj xyuas thaum lawv nce los ntawm lub cuab yeej, lees tias kev ua haujlwm ntawm lub cuab yeej lossis taw kev ua txhaum hauv lub cuab yeej. Cov tsim hluav taws xob rau kev siv hluav taws xob kuj siv los tsav cov khoom siv xws li hloov chaw, cov lasers thiab cov khoom siv kho qhov muag, cov qauv hloov kho, cov khoom siv sab nraud thiab ntxiv cov tsis kam tiv taus. Kev tsim tawm ntawm lub tshuab hluav taws xob (pulse generator) kuj tseem siv tau los ua qhov ntsuas qhov ntsuas rau lub teeb hluav taws xob. Cov ntawv thov tsis siv khoom siv hluav taws xob suav nrog cov khoom siv science, kho mob, physics thiab chemistry.
