Kuzinhlelo ezinomsindo, izigaba zangaphambili nezingemuva ziyimiqondo emibili ebalulekile edlala indima ebalulekile ekuqondiseni ukugeleza kwezimpawu zomsindo. Ukuqonda izindima zezigaba zangaphambili nezingemuva kubalulekile ekwakheni izinhlelo zomsindo ezisezingeni eliphakeme. Le ndatshana izolungisa ukubaluleka nezindima zezigaba zangaphambili ezingemuva ku-audio.
Umqondo we-Pre - namazinga wePosi
Isiteji sangaphambili: ezinhlelweni zomsindo, isiteji sangaphambili sivame ukubhekisela ekupheleni kokufaka kwesiginali yomsindo. Inesibopho sokuthola amasiginali omsindo avela emithonjeni ehlukene (efana nabadlali be-CD, amadivaysi e-Bluetooth, noma ama-televincilog) futhi abacubungula kwifomu elilungele ukucubungula okulandelayo. Umsebenzi wesiteji sangaphambili ufana nalowo wesikhungo sokucubungula esinomsindo kanye nesikhungo sokulungisa, esingashintsha ivolumu, ibhalansi, namanye amapharamitha wesiginali womsindo ukuqinisekisa ukuthi isibonakaliso somsindo sifinyelela isimo saso esifanele ekucutshungweni okulandelayo.
Isiteji sePosi: Uma kuqhathaniswa nesigaba esedlule, isigaba seposi sibhekisela emuva emuva kweketanga lokucubungula isiginali yomsindo. Ithola amasiginali omsindo asetshenzwe ngaphambili futhi ibakhipha kumadivayisi alalelwayo afana nezikhulumi noma amahedfoni. Umsebenzi wesiteji seposi ukuguqula isibonakaliso somsindo esisetshenzisiwe sibe msindo, ukuze sibonakale ngohlelo lokuzwakalayo. Isigaba sokugcina sivame ukufaka amadivaysi afana nama-amplifiers nezikhulumi, ezibhekele ukuguqula amasiginali kagesi abe amasiginali anengqondo futhi awadlulisele ngezikhulumi.
- yiqhaza lezigaba zangaphambili nezingemuva
Indima yeleveli eyandulele:
1 Ngokushintsha isigaba sangaphambili, isiginali yomsindo singalungiselelwe futhi sashintshwa ukuze sihlangabezane nezidingo zokucubungula nokukhishwa okulandelayo.
2. Ukukhethwa komthombo wesiginali: Ukuphela kwangaphambili kuvame ukuba neziteshi eziningi zokufaka futhi ungaxhuma amadivayisi alalelwayo kwimithombo ehlukahlukene. Ngokuphela kwangaphambili, abasebenzisi bangashintsha kalula phakathi kwemithombo ehlukene yomsindo, njengokushintsha kusuka ku-CD kuya kumsakazo noma i-Bluetooth Audio.
3. Ukuthuthukisa ikhwalithi yomsindo: Idizayini enhle yokuphela ingathuthukisa ikhwalithi yamasiginali alalelwayo, abenze bacace, bathembeke ngokwengeziwe, futhi bacebile. Ukuphela kwangaphambili kungathuthukisa ikhwalithi yezimpawu zomsindo ngochungechunge lwamasu wokucubungula wesiginali, ngaleyo ndlela kunikeze isipiliyoni esingcono sokuzwa.
Indima yesigaba esingemuva:
1. I-Signal Amplification: I-amplifier yamandla esiteji yakamuva inesibopho sokukhulisa isibonakaliso somsindo sokufaka ukufeza izinga elanele lokushayela isipika. I-amplifier ingakhulisa ngosayizi nohlobo lwesiginali yokufaka ukuze kuqinisekiswe ukuthi umsindo wokuphuma ungafinyelela izinga levolumu elindelekile.
2. Umsindo Okhipha: Isigaba esingemuva siguqula isiginali yomsindo esikhulisiwe sibe ngumsindo ngokuxhuma amadivaysi okukhipha njengezikhulumi, futhi akhiphe emoyeni. Isikhulumi sakha ukudlidliza ngokususelwa kusiginali kagesi esitholakele, ngaleyo ndlela sikhiqize umsindo, sivumela abantu ukuzwa okuqukethwe okuzwakalayo okuqukethwe ku-Audio Signal.
I-3. Ukusebenza kwekhwalithi ephezulu Kungaqinisekisa ukuthi amasiginali omsindo akhulisiwe ngaphandle kokuhlanekezela, ukuphazamiseka, futhi alondoloze ukwethembeka kwawo okuphezulu okuphezulu nokunemba ngesikhathi sokukhipha.
---- Isiphetho
Ezinhlelweni zomsindo, izigaba zangaphambili nezingemuva zidlala indima ebaluleke kakhulu, ngokubambisana nendlela yokugeleza kwezimpawu zomsindo ngaphakathi kohlelo. Ngokucutshungulwa kanye nokulungisa i-Front-End, isiginali yomsindo singalungiswa futhi salungiswa; Izinga lokugcina libhekele ukuguqula isiginali yomsindo esetshenzisiwe ibe msindo futhi avele. Ukuqonda nokulungiselela kahle izigaba zangaphambili nangemuva kungathuthukisa kakhulu ukusebenza kwekhwalithi nekhwalithi yomsindo, ukuhlinzeka abasebenzisi ngesipiliyoni esingcono somsindo.
