XHUMANA MANJE

Ama-attenuators alawulwa yi-voltage angamadivayisi esekethe adidiyelwe angalawula izinga lokuncishiswa kwamasiginali aphumayo ngamasiginali wokufakwayo wangaphandle. Izici zayo eziyinhloko kanye nezicelo zimi kanje:

Izici:

1. Ukulungiswa: Izibambisi ezilawulwa yi-voltage zilungisa izinga lokuncishiswa kwesiginali yokuphuma kwayo ngamasignali kagesi wokufakwayo wangaphandle, okuvumela ukulungiswa okunembayo nokulawula.
2. Umugqa womugqa ophezulu: Kunobudlelwano obuphezulu bomugqa phakathi kwe-voltage yokufaka nokuncishiswa kokuphumayo, okwenza izibambisi ezilawulwa yi-Voltage zinembe kakhulu futhi zizinzile ezinhlelweni zokusebenza.
3. Umkhawulokudonsa obanzi: Ama-attenuators alawulwa yi-voltage anempendulo enhle yomugqa ebangeni lemvamisa, ngakho-ke angasetshenziswa ezinhlobonhlobo zamasiginali.
4. Umsindo ophansi: Ngenxa yokusetshenziswa kwezingxenye zomsindo ophansi ekwakhiweni kwesekethe yangaphakathi ye-Voltage controlled attenuators, I-Voltage controlled attenuators ibonisa izinkomba zomsindo ophansi kakhulu phakathi nokusebenza.
5. Ukuhlanganiswa: Izibambisi ezilawulwa yi-voltage zingahlanganiswa kwezinye izifunda, okuholela kumthamo omncane nokuhlanganiswa okuphezulu kwalo lonke uhlelo.

Isicelo:

1. Uhlelo lokuxhumana: Izibambisi ezilawulwa yi-voltage zingasetshenziswa ukulungisa amandla esignali ohlelweni lokuxhumana, ukufeza ukulawulwa kwesignali nokulawula ngesikhathi sokudlulisa idatha nokwamukela.
2. Ukulawulwa komsindo: Izibambisi ezilawulwa yi-voltage zingasebenza njengeyunithi yokulawula umsindo ohlelweni lomsindo ukuze ulawule ukuncishiswa kwamasignali omsindo.
3. Isilinganiso sensimbi: Izibambisi ezilawulwa yi-voltage zingasetshenziswa njengengxenye yokulawula ekulinganisweni kwensimbi ukuze kulawulwe ngokunembile futhi kulungiswe amasignali, kuzuzwe ukunemba kwensimbi nokuzinza.
4. Ukucutshungulwa komsindo: Ama-attenuators alawulwa yi-voltage angasetshenziswa ekucubunguleni umsindo, njengama-synthesizer, ama-distortors, ama-compressor, njll.

Qualwaveihlinzeka ngebhendi ebanzi kanye nama-attenuators aphezulu aguquguqukayo alawulwa ngamaza kumafrikhwensi afika ku-40GHz. Ama-attenuators ethu alawulwa yi-voltage asetshenziswa kabanzi ezindaweni eziningi.
