GHz vs MHz

GHz thiab MHz sawv cev rau Gigahertz thiab Megahertz feem. Ob chav ntsuas no yog siv los ntsuas qhov zaus. Gigahertz thiab megahertz yog siv nyob rau hauv ntau qhov xwm txheej, los ntsuas qhov zaus hauv qhov sib txawv. Qhov zaus yog qhov tseem ceeb heev ntawm nthwv dej lossis kev vibration. Lub tswv yim ntawm zaus yog siv dav hauv kev lag luam xws li physics, engineering, astronomy, acoustics, electronics thiab ntau yam haujlwm. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv lub tswv yim ntawm zaus thiab cov units siv los ntsuas nws thiaj li ua tau zoo hauv cov haujlwm no. Hauv tsab xov xwm no, peb yuav tham txog dab tsi zaus yog dab tsi, GHz thiab MHz yog dab tsi, lawv cov ntawv thov, qhov zoo sib xws ntawm GHz thiab MHz, thiab thaum kawg qhov txawv ntawm GHz thiab MHz.

MHz (megahertz)

Chav tsev megahertz yog siv los ntsuas qhov zaus. Nws yog ib qho tsim nyog kom nkag siab txog lub tswv yim ntawm megahertz kom nkag siab txog chav tsev megahertz. Frequency yog ib lub tswv yim sib tham nyob rau hauv lub sij hawm motions ntawm cov khoom. Ib qho lus tsa suab tuaj yeem suav tias yog ib qho kev txav uas rov ua nws tus kheej hauv lub sijhawm teem tseg. Lub ntiaj teb revolving ib ncig ntawm lub hnub yog ib tug periodic motion. Lub satellite orbiting nyob ib ncig ntawm lub ntiaj teb yog ib tug periodic motion, txawm lub suab ntawm ib tug tshuav pob teeb yog ib tug periodic motion. Feem ntau ntawm cov lus tsa suab peb ntsib yog ncig, linear lossis semi-circular. Ib qho kev txav mus los muaj ntau zaus. Qhov zaus txhais tau tias yuav ua li cas "frequent" tshwm sim. Rau qhov yooj yim, peb siv zaus raws li qhov tshwm sim ib ob. Cov lus tsa suab ib ntus tuaj yeem yog ib yam lossis tsis sib xws. Ib tug uniform ib tug yuav muaj ib tug uniform angular tshaj tawm. Cov haujlwm xws li amplitude modulation tuaj yeem muaj ob lub sijhawm. Lawv yog cov haujlwm ua ntu zus nyob rau hauv lwm cov haujlwm raws sijhawm. Qhov kev hloov pauv ntawm qhov zaus ntawm lub sijhawm ua haujlwm muab lub sijhawm rau ib lub sijhawm. Chav tsev tau raug hu ua hertz kom hwm tus neeg German physicist Heinrich Hertz. Chav tsev Megahertz yog sib npaug rau 10 6hertz. Chav tsev Megahertz tau dav siv los ntsuas zaus ntawm xov tooj cua thiab TV tshaj tawm xov tooj cua tsis muaj zog thiab ceev ntawm microprocessors.

GHz (Gigahertz)

Gigahertz kuj yog ib chav siv los ntsuas zaus. Lub npe "Giga" yog hais txog qhov tseem ceeb ntawm 10 9 Li no, chav tsev Gigahertz yog sib npaug rau 10 9hertz. Ib qho khoom siv hauv tsev neeg tus kheej muaj lub zog ua haujlwm ntawm Gigahertz. Xov tooj cua nthwv dej kuj raug ntsuas hauv GHz thaum siv xov tooj cua zaus hloov pauv ntau zaus.

Qhov txawv ntawm MHz thiab GHz yog dab tsi?

• Ob leeg Megahertz thiab Gigahertz yog siv los ntsuas zaus. MHz yog 1000 npaug qis dua GHz.

• Electromagnetic yoj hauv cheeb tsam ntawm GHz muaj ntau lub zog ib photon tshaj li ntawm MHz ntau.

• GHz tau siv dav los ntsuas tsev neeg thiab chaw ua haujlwm khoos phis tawj 'kev suav lub zog ntawm lub processor. MHz tau dav siv los ntsuas lub zog ua haujlwm ntawm microprocessors.

• Megahertz sawv cev 10 6 hertz, whereas Gigahertz sawv cev 10 9hertz.
