Ma Voltage Controlled Attenuators
Ma attenuators oyendetsedwa ndi ma voliyumu ndi zida zophatikizika zozungulira zomwe zimatha kuwongolera kuchuluka kwa ma siginecha omwe amatuluka kudzera pamagetsi olowera kunja. Makhalidwe ake akuluakulu ndi ntchito zake ndi izi:
Mawonekedwe:
1. Kusintha: Othandizira owongolera magetsi amasintha kutsika kwa siginecha yake yotulutsa kudzera pamagetsi olowera kunja, kupangitsa kusintha kolondola ndi kuwongolera.
2. Mzere wapamwamba: Pali mgwirizano wapamwamba pakati pa magetsi olowera ndi kuchepetsedwa kwa zotulutsa, zomwe zimapangitsa kuti magetsi oyendetsedwa ndi Voltage akhale olondola kwambiri komanso okhazikika pamagwiritsidwe ntchito.
3. Wide bandwidth: Ma attenuator oyendetsedwa ndi magetsi amakhala ndi mayankho abwino a mzere mumayendedwe pafupipafupi, kotero amatha kugwiritsidwa ntchito pazizindikiro zambiri.
4. Phokoso laling'ono: Chifukwa cha kugwiritsidwa ntchito kwa zigawo za phokoso laling'ono mu mapangidwe apakati a Voltage controlled attenuators, Voltage controlled attenuators amasonyeza zizindikiro za phokoso lochepa kwambiri panthawi ya ntchito.
5. Integratability: Magetsi oyendetsedwa ndi magetsi amatha kuphatikizidwa muzitsulo zina, zomwe zimapangitsa kuti pakhale phokoso laling'ono komanso kusakanikirana kwakukulu kwa dongosolo lonse.
Ntchito:
1. Njira yolumikizirana: Ma attenuators oyendetsedwa ndi magetsi amatha kugwiritsidwa ntchito kusinthira mphamvu yazizindikiro munjira yolumikizirana, kukwaniritsa kuwongolera ndi kuwongolera pamayendedwe a data ndi kulandira.
2. Kuwongolera ma audio: Othandizira owongolera ma Voltage amatha kukhala ngati gawo lowongolera ma audio mumayendedwe amawu kuti athe kuwongolera kuchepetsedwa kwa ma audio.
3. Kuyeza kwa zida: Magetsi oyendetsedwa ndi magetsi amatha kugwiritsidwa ntchito ngati gawo lowongolera muyeso la zida kuti azitha kuwongolera molondola ndikusintha ma signature, kukwaniritsa kulondola kwa zida ndi kukhazikika.
4. Kukonza phokoso: Magetsi oyendetsedwa ndi magetsi amatha kugwiritsidwa ntchito pokonza phokoso, monga synthesizer, distortors, compressors, etc.
Qualwaveimapereka bandi yotakata komanso ma attenuators apamwamba kwambiri owongolera ma voltage pa ma frequency mpaka 40GHz. Ma attenuators athu oyendetsedwa ndi magetsi amagwiritsidwa ntchito kwambiri m'malo ambiri.
