Quantizer thaiv discretizes lub teeb liab tawm tswv yim siv quantization algorithm Lub thaiv siv ib puag ncig-rau-ze tshaj txoj kev los qhia cov teeb liab qhov tseem ceeb rau quantized qhov tseem ceeb ntawm cov zis uas tau txiav txim los ntawm Lub sijhawm Quantization. Lub teeb liab sib xyaw ua ke tuaj yeem ua rau tus ntaiv-kauj ruam zoo tom qab quantization.

Yuav ua li cas koj npaj cov quantizer hauv Matlab?

y=quantize(q, x) siv cov khoom quantizer q kom quantize x. Thaum x yog tus lej array, txhua lub ntsiab ntawm x yog quantized. Cov zis y yog xa rov qab raws li ib tug built-in ob. Thaum x yog cell array, txhua tus lej ntawm cov xov tooj ntawm tes yog quantized.

Dab tsi yog quantizer hauv Simulink?

Kev piav qhia. Lub Quantizer thaiv passes nws cov teeb liab tawm tswv yim los ntawm kev ua haujlwm stair-stepkom ntau cov ntsiab lus nyob sib ze ntawm lub tswv yim axis tau mapped rau ib qho ntawm cov zis axis. Cov nyhuv yog kom quantize ib tug du teeb liab rau hauv ib tug stair-step tso zis.

Dab tsi yog quantization thiab vim li cas nws thiaj siv?

Quantization yog txheej txheem ntawm daim ntawv qhia qhov tseem ceeb tsis tu ncua mus rau ib qho me me ntawm cov txiaj ntsig tsis sib xws. … Quantization qhia txog ntau qhov kev ua yuam kev hauv koj lub algorithm, xws li kev ua yuam kev, qis qis lossis dhau mus, suav cov suab nrov, thiab kev txwv tsis pub dhau.

Lub hom phiaj ntawm kev txiav txim yog dab tsi?

Quantization yog txheej txheem ntawm kev hloov pauv ntau yam ntawm cov txiaj ntsig mus rau qhov kawg ntawm qhov tsis pom zoo. Qhov no yog ib qho kev ua haujlwm ntawm analog-rau-digital converters, uas tsim ib tug series ntawm cov txiaj ntsig digital los sawv cev tus thawj analog teeb liab.
