Uyini umehluko phakathi kwesipikha sebanga eligcwele nesipikha sefrikhwensi esiyingxenye?
一, isipikha sefrikhwensi esiyingxenye
Izipikha zokusabalalisa imvamisa, isipikha esijwayelekile esinezindlela ezimbili, isipikha sendlela-ntathu, ngesihlukanisi esakhelwe ngaphakathi, amasiginali omsindo webanga lefrikhwensi ahlukene ayahlukaniswa, bese adluliselwa kusipika esihambisanayo. Ubuhle besipikha sefrikhwensi eyingxenye ukuthi ibhendi ngayinye yefrikhwensi ineyunithi yayo yomsindo, ngalinye lenza imisebenzi yalo futhi linikeza umdlalo ngezinzuzo zebhendi yalo yefrikhwensi.

1,Isipikha esinezindlela ezimbili
Isetshenziselwa ama-acoustics eshalofu lezincwadi, isipikha sefrikhwensi esiyingxenye sineyunithi ehlukile ye-treble, futhi amabhesi aphakathi ahlanganiswe ndawonye. Ngenxa yokuthi iyunithi ye-treble neyunithi ye-bass zihlukene, lesi sici sesakhiwo senza ukunaba kwamafrikhwensi aphezulu naphansi kube ngcono, ukusuka entweni eyedwana ukuya ku-symphony yokuhlanganisa enkulu, kungethulwa kahle.
2,Isipikha sezindlela ezintathu
Ineyunithi yomsindo emaphakathi eyengeziwe ehlobene nefrikhwensi yesibili, ngakho futhi inokusebenza kwemininingwane yomsindo engcono. Ukuze kuzuzwe umphumela omuhle wekhwalithi yomsindo, abakhiqizi abaningi basebenza kanzima endaweni yokuhlukanisa imvamisa. Ukukhethwa kwephuzu lokuhlukanisa imvamisa kufanele kuthathwe ngokuya ngezimpawu zokuphendula kwemvamisa yeyunithi yesipika. Uma ingasethiwe kahle, izophazamisa ukusatshalaliswa kwamandla omsindo, okuholela ekutheni imvamisa yomsindo ingabi flat. Ngaphandle kohlelo lwesayensi noluphusile lokuhlukanisa imvamisa, ngisho neyunithi yesipikha ehamba phambili, ngeke ihlanganiswe ukuze isebenze. Kuphela ngokuhlukaniswa okuningiliziwe kwefrikhwensi, iyunithi ehambisanayo ingabuyisela umsindo webhendi ngayinye yefrikhwensi, futhi ukusebenza kwekhwalithi yomsindo kuzoba ngcono. Ngenxa yokuthi kunamayunithi ama-frequency amathathu, i-frequency divider nayo idinga inkimbinkimbi, izindleko ziphakeme, intengo yomsindo we-audio ye-frequency emithathu emakethe yamanje iyinkulungwane yokuqala ye-yuan, uphawu oludumile lufinyelelwa ezingeni lama-yuan ayizinkulungwane eziyishumi, kungashiwo ukuthi umkhuhlane awupheli. Njengamanje, kunezinhlobo eziningi zemikhiqizo yesipikha sendlela yomoya, njengomsindo we-KTV, ibhokisi leshalofu lezincwadi, umsindo wetiyetha wasekhaya osuka phansi kuya phansi nokunye.
二、isipika sobubanzi obugcwele
Njengoba igama liphakamisa, isipikha sefrikhwensi egcwele sisebenzisa kuphela isipikha sefrikhwensi egcwele singakhipha imvamisa ephezulu, emaphakathi, ephansi kanye namanye amaza omsindo. Nakuba ibizwa ngokuthi i-full frequency, ayikwazi ukumboza wonke ama-frequency band, i-frequency egcwele ibhekisela ebangeni elibanzi le-frequency kanye nokuhlanganisa okubanzi.Isipika sobubanzi obugcwele Idigri yokuhlanganisa isikhulumi iphezulu, isigaba sinembile ngokuqhathaniswa, i-timbre yebhande ngalinye le-frequency ivame ukuhambisana, futhi izinga lokuhlanekezela izindlebe liphansi. Ikakhulukazi, ukusebenza kwengxenye yefrikhwensi ephakathi kuhle kakhulu, futhi umsindo okhishwa abantu ikakhulukazi uphakathi nendawo, ngakho izwi lomuntu ligcwele futhi lingokwemvelo. Ngakho-ke, isipikha esigcwele ububanzi sisetshenziswa kakhulu kumsindo we-TV (ibha yomsindo), engathuthukisa futhi ithuthukise imiphumela yomsindo yamasethi we-TV.
