Hom teeb liab kis tau los ntawm cov khoom siv hluav taws xob muaj xws li hluav taws xob teeb liab, cov teeb liab sib nqus, cov teeb liab kho qhov muag, thiab cov teeb liab suab.
Hluav taws xob teeb liab: Ib qho hluav taws xob teeb liab yog hais txog cov ntaub ntawv xa mus rau hauv daim ntawv ntawm tam sim no lossis voltage hauv ib lub voj voog. Cov khoom siv hluav taws xob tuaj yeem tsim hluav taws xob teeb liab xws li tam sim no ncaj qha, hloov tam sim no, thiab hluav taws xob mem tes. Piv txwv li, cov khoom siv semiconductor xws li diodes, transistors, thiab lwm yam tuaj yeem tsim DC hluav taws xob teeb liab; Oscillators, transformers, thiab lwm yam khoom siv tuaj yeem tsim cov kev hloov pauv tam sim no; Digital circuits xws li cov txee thiab timers tuaj yeem tsim cov cim mem tes.
Magnetic signal: Sib nqus teeb liab yog hais txog cov ntaub ntawv xa mus rau hauv daim ntawv ntawm magnetization los yog magnetic teb hloov nyob rau hauv ib tug magnetic teb. Cov khoom siv hluav taws xob tuaj yeem tsim cov chaw sib nqus thiab cov teeb liab sib nqus los ntawm qhov ntws ntawm qhov tam sim no. Piv txwv li, cov khoom siv hluav taws xob xws li lub cev muaj zog thiab cov khoom siv hluav taws xob tuaj yeem tsim cov teeb liab sib nqus.
Optical signal: Optical signal yog hais txog cov ntaub ntawv xa mus rau hauv daim ntawv ntawm kev hloov pauv ntawm qhov siv, zaus, theem, thiab lwm yam ntawm lub teeb teeb. Cov khoom siv hluav taws xob tuaj yeem tsim cov teeb liab kho qhov muag los ntawm cov hauv paus ntsiab lus xws li photoelectric effect thiab photoconductive effect. Piv txwv li, cov khoom xws li lub teeb-emitting diodes (LEDs), photodiodes (PDs), thiab laser diodes tuaj yeem tsim teeb pom kev zoo.
Lub suab teeb liab: Lub suab teeb liab yog hais txog cov ntaub ntawv xa mus rau hauv daim ntawv ntawm kev hloov pauv hauv acoustic tsis xws li amplitude thiab zaus ntawm lub suab nthwv dej. Cov khoom siv hluav taws xob tuaj yeem tsim cov suab paj nruag los ntawm cov thev naus laus zis xws li microphones thiab hais lus.
