Kugwiritsa ntchito ukadaulo wa DSP mu Mawayilesi a FM sichinthu chatsopano. Mutha kuziwona m'malo ambiri wailesi ya digito ya FM. Ndiye teknoloji ndi yotani? Gawoli liwonetsa DSP muzinthu zitatu: mfundo yogwirira ntchito ya DSP, kapangidwe kake ka DSP, ndi ntchito ya DSP.

Q&A
DS ndi chiyaniP?
DSP imatanthawuza ukadaulo wopanga ma siginecha a digito. Imatembenuza mawu olowera kukhala mawayilesi a FM kukhala ma siginecha 0 ndi 1, ndikuwongolera, monga kuwonjezera, kuchotsa, kuchulukitsa, ndi kugawa masamu, kenako kutulutsa siginecha ya digito ku DDS kuti ipitirire.
Poyerekeza ndi ukadaulo wamakina opangira ma analogi, DSP ili ndi maubwino owongolera ma siginecha olondola, kuthekera kotsutsana ndi kusokoneza, kuthamanga kwambiri pakutumiza mtunda wautali, ndi kupotoza kochepa. Chifukwa chake, ma wayilesi a FM okhala ndi ukadaulo wa DSP amatha kufalitsa ma siginecha amawu apamwamba kwambiri komanso osokonekera pang'ono, ndipo omvera kapena opanga ma wayilesi sangakhumudwe ndi phokoso. Chotero Mawayilesi a FM amagwiritsidwa ntchito kwambiri m'mawayilesi amzindawu, malo ochitira masewera olimbitsa thupi, ndi zina zotero.
Kodi DSP Ili Ndi Magawo Ati?
Dongosolo labwino kwambiri la DSP lili ndi magawo angapo osiyanasiyana: Zolowetsa ndi zotuluka, Chip cha DSP, Memory Program, Injini yamakompyuta, Kusungirako data. Ndipo ali ndi udindo pa ntchito zosiyanasiyana.
- Zolowetsa ndi zotuluka - Awa ndi zipata za ma wayilesi a FM kuti alandire ma siginecha amawu ndi ma sign a digito. Chizindikiro cha digito kapena chizindikiro cha digito chosinthidwa kuchokera ku siginecha ya analogi imalowa mudongosolo la DSP kudzera pakulowetsa, kukonzedwa, kenako ndikulowa mugawo lotsatira lokonzekera kudzera pazotuluka.
- Chithunzi cha DSP - Uwu ndiye "ubongo" wa DSP system, pomwe ma digito amasinthidwa.
- Memory - Apa ndipamene ma DSP digito processing algorithms amasungidwa.
- Kukumbukira kwa pulogalamu - Monga mapulogalamu ena okumbukira, mapulogalamu osinthira deta amasungidwa apa.
- Makina apakompyuta - Ichi ndi gawo la dongosolo la DSP, lomwe limagwiritsidwa ntchito kuwerengera masamu onse omwe amachitika popanga ma signature.
- Kusungirako deta - Zonse zomwe zingafunike kukonzedwa zasungidwa apa.
Dongosolo la DSP lili ngati malo opangira zinthu, omwe amafunikira kugawanika kwa ntchito ndi mgwirizano wa magawo osiyanasiyana asanayambe kukonza bwino chizindikiro cha digito.
Kodi DSP Ingatichitire Chiyani?
Tikudziwa kuti ukadaulo wa DSP umathandizira kufalikira kwamawu kudzera pakusintha kwa digito kwamasinthidwe amawu. Chifukwa chake ma transmitters a FM atha kugwiritsidwa ntchito muzochitika zambiri. Nazi zitsanzo:
- Simungathenso kuvutitsidwa ndi phokoso - Ukadaulo wa DSP umatha kusiyanitsa mawu ofunikira komanso maphokoso osokoneza, monga mapazi. Pazosokoneza zomwe zimachitika chifukwa chaphokoso, ukadaulo wa DSP ukhoza kutchingira ndikuwongolera SNR ya wailesi ya FM.
- Zingapangitse kuti voliyumu ikhale yokhazikika - Dongosolo la DSP lili ndi ntchito yowongolera zodziwikiratu. Ikhoza kusinthasintha mphamvu ya mawu kuti mawuwo asamveke kwambiri kapena akhale chete, zimene zingathandize kuti omvera amvetsere bwino.
- Limbikitsani kumveka kwa mawu pafupipafupi - Zida zosiyanasiyana zimakhala ndi kukhathamiritsa kosiyana kwamamvekedwe amtundu womwewo. Mwachitsanzo, ngati wailesi yakonzedwa kuti ikhale ndi mamvekedwe apamwamba kwambiri, mtundu wa mawu otsika kwambiri omwe umayimba ukhoza kukhala wocheperako. Ukadaulo wa DSP utha kulinganiza kukhathamiritsa uku ndikusintha kamvekedwe kakang'ono kawayilesi posintha mawu omvera.
- Zosinthika kumadera osiyanasiyana amawu - Ukadaulo wa DSP uli ndi kuthekera kosintha mawu m'malo osiyanasiyana, zomwe ndizofunikira kwambiri m'malo aphokoso ngati mafakitale.
- Zimakupulumutsirani malo ambiri - Ma transmitters a FM asanayambe kutengera ukadaulo wa DSP, zomveka zambiri zimazindikirika ndi zida zina zambiri. Koma tsopano ndi gawo laling'ono lokha lomwe likufunika kuti mukwaniritse bwino komanso zomveka zambiri.
The Mawayilesi a FM ndi ukadaulo wa DSP ukhoza kutithandiza kuthana ndi mavuto ochulukirapo, ndikupangitsa kuti chotumiziracho chizigwiritsidwa ntchito kuzinthu zambiri, monga mawayilesi apamzinda akatswiri, mawayilesi ammudzi, malo ochitira masewera olimbitsa thupi, tchalitchi ndi zina zotero.
Wopereka Zabwino Kwambiri pa Ma Transmitters a FM okhala ndi DSP Technology
The Wotumiza wailesi ya FM zokhala ndi DSP zitha kugwiritsidwa ntchito mosiyanasiyana pazithunzi zosiyanasiyana. Monga m'modzi mwa ogulitsa bwino kwambiri ma transmitters a FM okhala ndi ukadaulo wa DSP, FMUSER imatha kukupatsirani mayankho makonda malinga ndi momwe mumagwiritsira ntchito komanso akatswiri. mapaketi zida za wailesi kuphatikiza ma wayilesi a FM ndi DSP ogwira ntchito pawailesi. Ubwino wa mankhwala athu ndi wabwino mokwanira ndipo amalipira mitengo yotsika. Ngati mukufuna kupanga wayilesi yanu ndikugula Ma transmitter a FM ndiukadaulo wa DSP, omasuka kulumikizana nafe. Tonse ndife makutu!

Tikukhulupirira kuti nkhaniyi ikuthandizani kumvetsetsa ukadaulo wa DSP. Chonde pitilizani kutsatira FMSUER, ndipo tipitiliza kukusinthirani zambiri zokhudzana ndi zida zamawayilesi anu.
Q&A
Kodi zosefera pakupanga ma siginolo a digito ndi chiyani?
Pokonza ma siginoloji a digito, fyuluta ndi chipangizo chomwe chimachotsa zinthu zina zosafunika pa sigino.
Ndi mitundu yanji ya zosefera pakukonza ma siginolo a digito?
Pali mitundu iwiri yofunikira ya zosefera za digito: finite impulse response (FIR) ndi infinite impulse response (IIR).
Kodi kuipa kwa digito ndi chiyani?
Kuipa kogwiritsa ntchito ma signature a digito kumaphatikizapo izi:
