Cov lus pom zoo yog feem ntawm. lub amplifier output teeb liab rov qab mus rau amplifier input. Hauv. daim, a tawm tswv yim voltage divider txhais cov feem no. los ntawm cov zis rau input hloov teb.

Tsuas yog li ntawd, dab tsi yog lub tswv yim Circuit Court?

Hauv electronics, tawm tswv yim yog txhais raws li tus txheej txheem ntawm rov qab ib feem ntawm lub teeb liab tso zis los ntawm a Circuit Court los yog ntaus ntawv rov qab mus rau lub tswv yim ntawm qhov ntawd Circuit Court los yog ntaus ntawv. Tawm tswv yim tshuab tau dav siv hauv amplifier circuits , oscillators, txheej txheem tswj cov txheej txheem, thiab hauv ntau qhov chaw.

3 hom kev tawm tswv yim yog dab tsi? Muaj plaub hom kev tawm tswv yim tsim nyog:

• Kev tawm tswv yim tsis zoo - kho cov lus hais txog kev coj cwj pwm yav dhau los.
• Cov lus pom zoo - lees paub cov lus hais txog kev coj cwj pwm yav dhau los.
• Tsis zoo feedforward – kho cov lus hais txog kev ua tau zoo yav tom ntej.
• Zoo feedforward – lees paub cov lus hais txog tus cwj pwm yav tom ntej.

Hauv qhov no, kev tawm tswv yim op amp yog dab tsi?

Ib tug tsis zoo- cov lus teb amplifier (los yog feedbackamplifier ) yog electronic amplifier uas rho tawm afraction ntawm nws cov zis los ntawm nws cov tswv yim, yog li ntawd tsis zoo tawm tswv yim tawm tsam thawj lub teeb liab.

Cov lus teb hauv chaw ua haujlwm yog dab tsi?

Muab thiab txais tawm tswv yim yog ib tug haib toolat chaw ua haujlwm . Nws qhia cov neeg ua haujlwm txog lawv qhov kev ua tau zoo thiab kev coj cwj pwm hauv pab pawg. Tawm tswv yim yuav tsum tau pib thiab tau txais nyob rau hauv tag nrho cov lus qhia nyob rau hauv ib tug hierarchy: los ntawm cov phooj ywg topeers, los ntawm cov neeg ua hauj lwm mus rau cov thawj coj, los ntawm cov thawj coj mus rau cov neeg ua hauj lwm.
