Harmonics Ib qho kev sib haum xeeb yog ib qho ntawm ib qho kev nce qib ntawm cov khoom siv sonic uas suab nrov tshaj qhov nrov zaus. Qhov ntau zaus harmonics uas suab saum lub hauv paus tsim lub harmonic spectrum harmonic spectrum A harmonic spectrum yog ib spectrum uas muaj cov zaus Cheebtsam uas nws frequencies yog tag nrho cov zauv ntau ntau ntawm cov zaus zaus; cov zaus no hu ua harmonics. "Cov ib feem ntawm tus kheej tsis hnov txog tab sis tau muab sib xyaw ua ke los ntawm pob ntseg rau hauv ib lub suab." https://en.wikipedia.org › wiki › Harmonic_spectrum
Harmonic spectrum - Wikipedia
ntawm lub suab. … Harmonics muaj qhov amplitude qis dua qhov zaus.
Puas yog qhov tseem ceeb tshaj plaws?
Vim qhov tseem ceeb yog qhov qis tshaj plawsthiab tseem pom tau tias yog qhov nrov tshaj plaws, pob ntseg qhia tias nws yog lub suab tshwj xeeb ntawm suab paj nruag [harmonic spectrum]…. Cov neeg ib feem tsis tau hnov dab tsi tab sis raug muab sib xyaw los ntawm pob ntseg rau hauv ib lub suab.
Dab tsi yog tag nrho cov resonant frequencies siab dua qhov tseem ceeb zaus?
Qhov qis tshaj resonant zaus hu ua qhov tseem ceeb, thaum tag nrho cov resonant ntau zaus hu ua overtones. Tag nrho cov resonant zaus yog ib qho sib npaug ntawm qhov tseem ceeb, thiab lawv raug hu ua harmonics.
Puas yog cov zaus zaus yog qhov qis tshaj plaws?
Qhov qis tshaj plaws uas tsim los ntawm ib qho cuab yeej tshwj xeeb yog hu ua qhov zaus zaus. Lub hauv paus zaus tseem hu ua thawj harmonic ntawm ntsuas.
Qhov zaus ntawm qhov zaus yog dab tsi?
The fundamental zaus (n=1) is ν=v/2l. Cov zaus ntau dua, hu ua harmonics lossis overtones, yog ntau qhov tseem ceeb. Nws yog kev cai xa mus rau lub hauv paus raws li thawj harmonic; n=2 muab qhov thib ob harmonic lossis thawj overtone, thiab lwm yam.

Puas yog alanine tseem ceeb lossis tsis tseem ceeb?
No tseem ceeb amino acids suav nrog: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, thiab tyrosine. Cov tshuaj amino acids feem ntau tsis tseem ceeb, tshwj tsis yog thaum muaj mob thiab kev ntxhov siab .
Nyob rau hauv lub cev kaw cov yeeb nkab qhov zaus ntawm qhov tseem ceeb?
Kaw lub cev yeeb nkab yog ib qho uas tsuas yog ib qho kawg qhib thiab lwm qhov yog kaw thiab suab dhau. Tam sim no, rau lub cev kaw cov yeeb nkab, qhov tseem ceeb zaus tau muab ν=v4L, qhov 'v' yog qhov nrawm ntawm lub suab hauv nruab nrab ntawm lub cev yeeb nkab thiab 'L' yog qhov ntev ntawm cev .
Dab tsi yog qhov tseem ceeb thiab tsis tseem ceeb?
Qhov me dua p-tus nqi, qhov muaj zog pov thawj uas koj yuav tsum tsis lees paub qhov kev xav tsis tseeb. Ib qho p-tus nqi tsawg dua 0.05 (feem ntau ≤ 0.05) yog qhov tseem ceeb. … A p-tus nqi siab dua 0.05 (> 0.05) tsis yogqhov tseem ceeb thiab qhia cov pov thawj muaj zog rau qhov kev xav tsis zoo .
Puas yog qhov tseem ceeb tseem ceeb cuam tshuam?
Qhov tseem ceeb tseem ceeb tshaj plaws (aka core prime implicants) yog prime implicants uas npog cov txiaj ntsig ntawm kev ua haujlwm uas tsis muaj kev sib xyaw ua ke ntawm lwm cov kev cuam tshuam tseem ceeb tuaj yeem npog Cov txiaj ntsig ntawm txhua qhov tseem ceeb Qhov cuam tshuam ntawm Boolean muaj nuj nqi yog hu ua nws cov nyiaj ua tiav, qhov tsawg kawg nkaus npog, lossis Blake canonical daim ntawv .
Vim li cas qhov tseem ceeb yog qhov tseem ceeb?
Nws yuav tsum muaj lub zog lub cev thiab lub siab lub ntsws. Qhov tseem ceeb yog qhov tseem ceeb uas tso cai rau koj mus txuas ntxiv thiab ua lub neej zoo. Hauv qhov tseem ceeb, qhov tseem ceeb txhais tau hais tias muaj zog, noj qab nyob zoo, thiab muaj txiaj ntsig zoo.
