Kev tsom xam Spectral lossis Spectrum tsom xam yog kev tshuaj xyuas ntawm cov spectrum ntawm ntau zaus lossis muaj feem cuam tshuam xws li lub zog, eigenvalues, thiab lwm yam.
Kev tsom xam spectral ua dab tsi?
Spectral tsom xam muab txhais tau tias ntsuas lub zog ntawm lub sijhawm (sinusoidal) cov khoom ntawm lub teeb liab ntawm ntau zaus. Lub Fourier hloov pauv yuav siv lub tswv yim ua haujlwm hauv lub sijhawm lossis qhov chaw thiab hloov pauv mus rau hauv txoj haujlwm nyuaj hauv zaus uas muab lub amplitude thiab theem ntawm cov tswv yim muaj nuj nqi.
Kev tsom xam spectral hauv cov ntaub ntawv tshawb fawb yog dab tsi?
In a nutshell, spectral method refers to a collection of algorithms build upon the eigenvalues (resp . … singular values) thiab eigenvectors (resp. singular vectors) ntawm qee qhov tsim qauv zoo tsim los ntawm cov ntaub ntawv.
DSP tsom xam spectrum yog dab tsi?
Spectral tsom xam yog txheej txheem ntawm kev kwv yees lub zog spectrum (PS) ntawm lub teeb liab los ntawm nws lub sijhawm sawv cev. Spectral density characterizes lub zaus cov ntsiab lus ntawm lub teeb liab lossis cov txheej txheem stochastic.
Kev tsom xam spectral hauv kev tshawb fawb txoj kev yog dab tsi?
Spectral tsom xam yog ib qho kev tshawb fawb tseem ceeb rau kev txiav txim siab cov ntaub ntawv hauv ntau yam kev tshawb fawb thiab thev naus laus zis. … Cov txheej txheem no tuaj yeem hloov cov ntaub ntawv sau mus rau spectral domain. Spectral tsom xam kawm cov spectral zaus nyob rau hauv discrete thiab uniformly sampled data.
