Yintoni iprosesa yesandi sedijithali?
Iprosesa yesandi sedijithali, okanye i-DSP, sisiprosesa esikhethekileyo esiyilwe ngowona msebenzi uphambili wokulawula imiqondiso yesandi kwisizinda sedijithali. Ngokungafaniyo neenkqubo zomsindo zemveli ezisebenza kunye neempawu ze-analog, ii-DSPs ziguqula le miqondiso kwifomathi yedijithali, ivumela uluhlu olubanzi lokuguqulwa kunye nokuphucula. Obu buchule benza ukuba ii-DSP zibaluleke kakhulu kwizicelo ezahlukeneyo, ukusuka kwimveliso yeaudio yobuchwephesha ukuya kubathengi be-elektroniki njengee-smartphones kunye neenkqubo zethiyetha yasekhaya.
Undoqo wokusebenza kwe-DSP usekukwazini kwayo ukwenza imisebenzi yezibalo enesantya esiphezulu kwimiqondiso yedijithali. Le nkqubo ibandakanya amanyathelo aliqela, kubandakanywa ukuhluza, ukulinganisa, kunye noxinzelelo oluguquguqukayo loluhlu, zonke zijolise ekuphuculeni umgangatho wesandi okanye ukufezekisa iziphumo ezithile zomsindo. Ukuguquguquka kunye nokuchaneka kwe-DSPs kuguqule imboni ye-audio, eyenza abadali kunye nabathengi bafezekise ukuthembeka kwesandi esingenakulinganiswa kunye nokwenza ngokwezifiso.
Ii-DSPs ziza ngeendlela ezahlukeneyo, ukusuka kwiiyunithi ezizimeleyo kunye neenkqubo ezizinzisiweyo ukuya ekuphunyezweni kwesoftware. Uhlobo ngalunye lusebenza kwiimfuno ezahlukeneyo kunye nezicelo, kodwa zonke zabelana ngeenjongo ezifanayo zokuphucula ukusebenza komsindo. Nokuba ikwindawo yokomelezwa kwesandi esiphilayo, isitudiyo sokurekhoda, okanye isixhobo somntu orekhodiweyo, ii-DSP zidlala indima ebalulekileyo ekuziseni amava esandi afanelekileyo.
Ingaba iprosesa yesandi sedijithali isebenza njani?
Kwisiseko sayo, iprosesa yesandi sedijithali ithatha izibonakaliso zomsindo we-analog, iguqulelwe kwifomathi yedijithali isebenzisa i-analog-to-digital converter (ADC), iqhuba idatha yedijithali, kwaye emva koko iyiguqulela kwifom ye-analog kunye ne-digital-to-analog converter (DAC) ukuze udlale. Le nkqubo yoguqulo ingundoqo ekusebenzeni kwe-DSP, ivumela ukuguqulwa kwemiqondiso yesandi ngokuchaneka kunye nokuguquguquka.
I-domain yedijithali inika indawo yokudlala yeendlela ezahlukeneyo zokucwangcisa umqondiso. Umzekelo, ukulinganisa kuvumela uhlengahlengiso lweebhendi ezithile zamaza, ukuziphucula okanye ukuthomalalisa ukufezekisa iprofayile yesandi efunwayo. Ukucoca, kwelinye icala, kunokususa amaza angafunekiyo okanye ingxolo kwisignali. Ukusetyenzwa kwe-Dynamics, kubandakanywa ukunyanzeliswa kunye nokunciphisa, kunceda ukulawula amanqanaba omsindo wesignali, ukuqinisekisa imveliso elinganayo kunye engaguqukiyo.
Ukucwangcisa kudlala indima ebalulekileyo ekuchazeni ukusebenza kweDSP. Ngee-algorithms ezintsonkothileyo, iinjineli zinokuyila iinkqubo ezenza imisebenzi entsonkothileyo, ukusuka ekulinganiseni imeko-bume ye-acoustic ukuya ekudaleni amava esandi esingqongileyo esintywilayo. Ukukwazi ukuhlaziya kunye nokuguqula ezi algorithms kwenza i-DSPs isebenze ngeendlela ezininzi, ikwazi ukuziqhelanisa nobuchwepheshe obutsha kunye nobuchule bokwenza umsindo.
Izibonelelo kunye nokungahambi kakuhle kweeprosesa zesandi sedijithali
Iiprosesa zesandi sedijithali zibonelela ngentaphane yeenzuzo, eyona nto iphambili phakathi kwazo kukukwazi ukufikelela kwisandi esikumgangatho ophezulu. Ngokulawula ngokuchanekileyo imiqondiso yesandi, ii-DSPs zinokuphucula ukucaca, ukususa ingxolo, kunye nesandi esilungelelanisiweyo ukuze silingane nendawo ethile okanye izinto ezikhethwayo. Eli nqanaba lolawulo liluncedo ngakumbi kwiisetingi zeaudio zobuchwephesha, apho umgangatho wesandi ungowona ubalulekileyo.
Enye inzuzo ebalulekileyo kukuguquguquka kunye nokwenza ngokwezifiso iiDSPs ezibonelela. Ngenkqubo efanelekileyo, i-DSP enye inokusebenza imisebenzi emininzi, ukusuka ekusebenzeni njenge-crossover kwinkqubo yesithethi ukubonelela ngesandi esijikelezayo kwi-headphones. Oku kuziqhelanisa kwandisa ukusebenziseka kwezixhobo zeaudio, kuvumela amava okuphulaphula obuqu.
Nangona kunjalo, ii-DSPs azinayo imiqobo yazo. Ubunzima bokulungiswa kwesignali yedijithali kunokwazisa i-latency, ukulibaziseka phakathi kwegalelo kunye neempawu zemveliso. Ngelixa kuncinci, oku kulibaziseka kunokuba yingxaki kwizicelo ezithile, ezinje ngokuqiniswa kwesandi esiphilayo. Ukongeza, umgangatho wokusebenza kwe-DSP uxhomekeke kakhulu kwii-algorithms ezisebenzisayo, ezinokwahluka ngokubanzi ekusebenzeni. Oku kuxhomekeka kwisoftware kuthetha ukuba ayizizo zonke ii-DSP ezidalwe zilingana, ezinye zibonelela ngesakhono sokulawula isandi esiphakamileyo kunezinye.
Indlela yokukhetha iprosesa yesandi sedijithali
Ukukhetha iprosesa yesandi esichanekileyo sedijithali kuxhomekeke kwizinto ezininzi, kubandakanya iimfuno zakho zomsindo, usetyenziso, kunye nohlahlo lwabiwo-mali lwakho. Kwabo bakwimveliso yeaudio yobuchwephesha, i-DSP enoluhlu olubanzi lwezakhono zokuqhuba kunye nabaguquli abakumgangatho ophezulu kunokuba yimfuneko. Ngokwahlukileyo, abaphulaphuli abaqhelekileyo banokubeka phambili ngokulula ukusetyenziswa kunye nokudityaniswa neenkqubo ezikhoyo zomsindo.
Xa ukhetha i-DSP, qwalasela amandla okusebenza kunye neentlobo ze-algorithms ezixhasayo.
