Raws li lub npe tau hais tseg, ib qho kev sib txawv ib leeg-kawg lub suab nrov amplifies lub teeb liab uas tau muab los ntawm tsuas yog ib qho ntawm cov tswv yim. Ua kom tiav Cov kauj ruam los ntawm kauj ruam kev daws teeb meem: Cov khoom siv ntawm ib qho kawg qhov sib txawv amplifier yog hauv av ntawm ib kawg thiab teeb liab ntawm lwm qhov kawg.
Dab tsi yog qhov sib txawv ntawm ib leeg xwb?
Ib qho ntawm ntau hom amplifier complex uas peb yuav kawm yog hu ua qhov txawv amplifier. Tsis zoo li ib txwm amplifiers, uas amplify ib lub tswv yim teeb liab (feem ntau hu ua ib leeg-kawg amplifiers), txawv amplifiers amplify qhov voltage txawv ntawm ob lub tswv yim signals.
Vim li cas cov kab hluav taws xob sib txawv tau nyiam dua li ntawm ib qho kawg?
Apart from qhov siab tshaj plaws ntawm txhua hom tso zis, muaj cov txiaj ntsig zoo rau kev siv kev sib txawv ntawm cov khoom siv thiab cov khoom tawm. Qhov zoo yog vim kom nce lub teeb liab viav vias, ntau dua slew tus nqi, thiab siv cov kab sib txawv sib txawv.
Dab tsi yog hom amplifier txawv?
Cov lus qhia nkag mus rau qhov sib txawv amplifier, feem ntau, muaj ob yam khoom; cov 'hom-hom' thiab 'difference-mode' signals. Hom-hom teeb liab yog qhov nruab nrab ntawm ob lub tswv yim teeb liab thiab qhov sib txawv hom yog qhov sib txawv ntawm ob lub tswv yim teeb liab.
Dab tsi yog 3 hom kev ua haujlwm ntawm lub teeb liab rau lub suab sib txawv?
Cov hom no tau piav qhia hauv qab no
- Kev Ua Haujlwm Ib Leeg. Thaum lub tshuab hluav taws xob sib txawv ua haujlwm hauv hom no, ib qho kev tawm tswv yim yog hauv av thiab cov teeb liab voltage tsuas yog siv rau lwm cov tswv yim. …
- Kev ua haujlwm sib txawv. …
- Hom Kev Ua Haujlwm. …
- Inverting thiab tsis-inverting inputs.
