O le a le DSP
DSP (Digital Signal Processing) e faasino i le faʻaogaina o komepiuta poʻo mea faʻapitoa e faʻaogaina e aoina ai, suia, faamama, faʻatusatusa, faʻaleleia, faʻapipiʻi, faʻamaonia ma isi faʻailoga i foliga numera e maua ai se faʻailoga faʻailoga e fetaui ma manaʻoga o tagata (embedded microprocessor). Talu mai le 1960s, faʻatasi ai ma le televave o le atinaʻeina o komepiuta ma faʻamatalaga faʻamatalaga, faʻatekonolosi DSP na tulaʻi mai ma faʻalauteleina vave. I le luasefulu tausaga ua tuanaʻi, ua faʻaaogaina tele le faʻaogaina o faailoilo numera i fesoʻotaʻiga ma isi matata.
Le lelei o tekinolosi DSP:
- Sa'o maualuga
- Gaoioiga maualuga
- Maualuga maualuga
- Taimi-vaega multiplexing
Fa'ailoga ole tekonolosi DSP:
1. Lagolago mo galuega fa'ateleina fa'atele
2. Fa'atulagaina o mea e manatua
3. Matasele e leai se ulu
4. Fa'akomepiuta fa'amautu
5. Faiga faʻapitoa faʻasalalauga
6. Va'aiga o le taimi e fa'ataunu'u ai
7. Seti fa'atonuga DSP fa'amautu
8. Manaoga mo meafaigaluega tau atinae
Talosaga:
O le DSP e fa'aaoga muamua i vaega o le fa'alogo leo, tautalaga tautala, RADAR, seismology, leo, SONAR, fa'ailoa leo, ma nisi fa'ailoga tau tupe. Mo se faʻataʻitaʻiga, Faʻasologa o Faʻailoga Faʻatekonolosi e faʻaaogaina mo le faʻapipiʻiina o tautalaga mo telefoni feʻaveaʻi, faʻapea foʻi ma le tuʻuina atu o tautalaga mo telefoni feʻaveaʻi.
Mo le In Vehicle Infotainment, o le DSP fa'afuainumera fa'aliloilo fa'apitoa e tu'uina atu ai le leo fa'apitoa, e pei o le fale tifaga, jazz, ma isi, ma e mafai fo'i e nisi ona maua le leitio fa'amalamalamaga maualuga (HD) ma le leitio satelite mo le fiafia tele o leo-va'aia. O le DSP faʻailoga numera faʻapipiʻi faʻaleleia le faʻatinoga ma le faʻaogaina o faiga faʻamatalaga i totonu o taʻavale, faʻaleleia le lelei o le leo ma le vitio, maua atili fetuutuunai ma vave faʻataʻamilosaga mamanu.
