Mabwalo okulitsa mphamvu amatenga gawo lalikulu pazida zamagetsi zosawerengeka, kuyambira zokulitsa nyimbo kupita ku ma transmitters.Kumvetsetsa mawonekedwe awo ndi ntchito zazikulu ndizofunikira kwa aliyense wokonda zamagetsi kapena katswiri.Mubulogu iyi, tifufuza za dziko lochititsa chidwi la mabwalo a amplifier mphamvu, ndikuwunika mawonekedwe awo akulu, mfundo zogwirira ntchito, ndi kagwiritsidwe ntchito.Chifukwa chake, kaya ndinu wophunzira kapena katswiri wofuna kudziwa zambiri, khalani olimba pamene tikuyamba ulendo wanzeruwu.
Kodi dera la amplifier mphamvu ndi chiyani?
Tisanafufuze za mawonekedwe awo, choyamba tifotokoze zomwe tikutanthauza ndi gawo la amplifier mphamvu.Mwachidule, dera la amplifier lamagetsi ndi gawo lamagetsi lomwe limakulitsa ma siginecha amagetsi kumlingo wapamwamba wamagetsi oyenera kuyendetsa katundu, monga cholankhulira kapena mlongoti.Nthawi zambiri, mabwalo amplifier amagetsi amatenga mawu otsika kwambiri kapena siginecha yolowera mawayilesi ndikukulitsa kwambiri kuti apereke mphamvu yofunikira pakugwiritsa ntchito.
Mphamvu amplifier dera mawonekedwe
1. Mphamvu zogwiritsira ntchito mphamvu: Mabwalo amplifier amphamvu amapangidwa kuti azigwira ntchito zapamwamba kwambiri poyerekeza ndi mitundu ina ya amplifiers.Kukhoza kwawo kupereka mphamvu zazikulu kumawathandiza kuyendetsa katundu wovuta bwino komanso modalirika.
2. Linearity: Ma amplifiers amphamvu amayesetsa kusunga molondola mawonekedwe ndi tsatanetsatane wa chizindikiro cholowetsa.Linearity ndiyofunikira kuti muchepetse kupotoza ndikuwonetsetsa kutulutsa mokhulupirika kwa chizindikiro choyambirira.
3. Kuchita bwino: Kuchita bwino ndikofunika kwambiri pamabwalo amplifier mphamvu chifukwa kumatsimikizira kusinthika kwa mphamvu yamagetsi kukhala mphamvu yotulutsa yothandiza.Ma amplifiers amphamvu kwambiri amachepetsa kuwononga mphamvu, potero amachepetsa kugwiritsa ntchito batri komanso kutentha kwapakati.
4. Bandwidth: Bandwidth ya dera la amplifier mphamvu imatanthawuza mafupipafupi omwe amatha kukulitsa mokhulupirika.Kutengera kugwiritsa ntchito, ma amplifiers amagetsi amatha kugawidwa ngati ma amplifiers omvera omwe amagwira ntchito mumtundu wa audio, kapena zokulitsa mphamvu zamagetsi zamagetsi zomwe zimagwiritsidwa ntchito pamakina opanda zingwe.
Ntchito zazikulu zamagetsi amplifier circuit
1. Kukula kwa chizindikiro: Ntchito yaikulu ya dera lamagetsi amplifier ndi kukulitsa chizindikiro ku mlingo wapamwamba wa mphamvu kuti athe kugonjetsa kulepheretsa kwa katundu, monga wokamba nkhani kapena antenna.Ma amplifiers amasunga kukhulupirika ndi mtundu wa chizindikiro cholowera pomwe amapereka mphamvu zokwanira kuyendetsa katunduyo.
2. Kufananiza kwa Impedance: Mabwalo amplifier mphamvu nthawi zambiri amakhala ndi netiweki yofananira kuti akwaniritse kusamutsidwa kwa mphamvu pakati pa amplifier ndi katundu.Izi zimatsimikizira kuti mphamvu zambiri zimafalitsidwa, kuchepetsa kusinkhasinkha ndi kutaya chizindikiro.
3. Kusintha kwa Signal: Magetsi amagetsi amatha kukhala ndi magawo owongolera ma siginecha kuti apititse patsogolo mawonekedwe a siginecha, kuchotsa phokoso, kapena kugwiritsa ntchito kusefa kwachindunji kuti agwirizane ndi zomwe atulutsa pa pulogalamu inayake.Magawo awa amatha kuphatikiza zoyambira, zofananira, kapena zosefera.
4. Zozungulira zodzitchinjiriza: Mabwalo amplifier mphamvu nthawi zambiri amakhala ndi zozungulira zodzitchinjiriza kuti ateteze kuwonongeka komwe kungachitike chifukwa chamagetsi ochulukirapo, apano, kapena kutentha.Njira zodzitetezerazi zimathandizira kukulitsa moyo wa amplifier ndikuwonetsetsa kuti zikugwira ntchito bwino.
Mapeto
Mwachidule, mabwalo amplifier mphamvu ndi zinthu zofunika kwambiri pamitundu yosiyanasiyana yama audio ndi ma RF.Makhalidwe awo, monga kugwiritsira ntchito mphamvu, mzere, mphamvu, ndi bandwidth, zimatanthawuza mphamvu zawo zogwirira ntchito.Kumvetsetsa ntchito zazikulu za amplifiers amphamvu, kuphatikizapo kukulitsa chizindikiro, kufananiza kwa impedance, kuyika chizindikiro ndi chitetezo, kumatithandiza kuzindikira kufunikira kwawo poyendetsa oyankhula, kutumiza zizindikiro ndi kupereka chidziwitso chapamwamba cha audio.Pomwe ukadaulo ukupita patsogolo, zokulitsa mphamvu zikupitilizabe kusinthika kuti zipereke magwiridwe antchito, kuchita bwino, komanso kusinthasintha pazinthu zambiri zamagetsi.
