Piav qhia: Tus cyclic codes yog subclass ntawm cov cai tawm . Nws yog tsim los siv cov lus tawm tswv yim hloov pauv cov npe. Piav qhia: A. cyclic code tuaj yeem tsim siv lub tshuab hluav taws xob polynomial thiab thaiv cov cai tuaj yeem tsim tawm siv cov tshuab hluav taws xob.
Ib yam li ib tus tuaj yeem nug, yam khoom muaj txiaj ntsig ntawm cyclic codes yog dab tsi?
Cyclic code . Hauv coding kev tshawb xav, a cyclic chaws yog thaiv chaws , qhov kev hloov pauv ntawm txhua kab lus muab lwm lo lus uas yog rau chaws . Lawv yog cov yuam kev-kho cov lej uas muaj algebraic khoom uas yooj yim rau kev ua yuam kev pom thiab kho.
Kuj Paub, qhov zoo ntawm cov lej cyclic yog dab tsi?
- Li no rau, loj n thiab k. yuav tsum tau siv (swb tom ntej)
- Cyclic lis dej num yog.
- Qhov Zoo: Nkag siab, txiav txim siab thiab ua lej yooj yim los ntawm kev hloov npe.
Kuj Paub, dab tsi yog linear block codes?
Hauv coding kev tshawb xav, a linear code yog qhov ua yuam kev-kho chaws rau leej twg tawm ua ke ntawm codewords kuj yog ib tug codeword. Cov kab lus hauv a linear block code yog thaiv ntawm cov cim uas tau encoded siv cov cim ntau dua li tus nqi qub yuav raug xa mus.
Cov cuab yeej ntawm txoj kab thaiv kab tawm yog dab tsi?
2. LUS QHIA LINEAR BLOCK CODEIn ib (n, k) linear block code : 1st feem ntawm cov khoom me me ib txwm zoo ib yam rau cov lus sib txuas kom xa mus. Qhov thib ob ntawm (n-k) cov khoom tau suav los ntawm cov ntawv me me raws li txoj cai encoding thiab hu ua parity bits.

Fuse block ua haujlwm li cas?
Fuse Thaiv - Automotive. Lub fuse thaiv tuaj yeem yog ywj siab, qhov twg txhua lub fused Circuit Court muaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, los yog ganged, qhov twg lub zog sib koom ntawm tag nrho cov circuits. Independent fuse blocks xav tau ob lub xov hlau khiav rau txhua lub fuse, ib qho los ntawm lub zog hluav taws xob, thiab ib qho mus rau cov khoom siv
Cov tsheb txawv txawv puas poob qis?
Saib qhov kev poob qis raws li feem pua ntawm kev yuav khoom tus nqi: Lub tsheb nruab nrab poob 46% ntawm nws tus nqi dhau 3 xyoos. [1] Cov tsheb txawv txawv tsis muaj nqis ntau dua li qhov ntawd, thiab feem ntau tsawg dua. Yog lawm, tib feem pua ntawm tus nqi yuav khoom loj dua yog cov nyiaj ntau dua
Dab tsi yog block thiab tackle system?
Ib qho thaiv thiab tiv thaiv lossis tsuas yog cuam tshuam yog lub kaw lus ntawm ob lossis ntau lub pulleys nrog cov hlua lossis cov hlua txuas ntawm lawv, feem ntau yog siv los nqa cov khoom hnyav. Lub pulleys tau sib sau ua ke los tsim cov blocks thiab tom qab ntawd cov blocks yog ua ke kom ib qho ruaj khov thiab ib qho txav nrog lub nra
Lub linear compensator ua dab tsi?
Ib tus neeg them nyiaj rov qab ncaj qha yog cov cuab yeej muzzle uas tau tsim los rau roj ncaj qha thiab cuam tshuam rau pem hauv ntej ntawm tus tua.
