Sib npaug Isotropically Radiated Power
Hauv qhov no, EIRP sawv cev rau dab tsi?
Siv Isotropic Radiated Fais Fab
Tsis tas li, EIRP suav nrog li cas? Piv txwv li, piv txwv li, lub zog hluav taws xob yog ntsuas rau lub kav hlau txais xov arbitrary. Piv txwv tias lub zog siab tshaj plaws yog ntsuas ntawm = = 90 degrees, thiab tus nqi yog EIRP = 20 dBm = -10 dB = [0.1 W = 100 mW].
Tom qab ntawd, ib tus tuaj yeem nug, qhov txawv ntawm ERP thiab EIRP yog dab tsi?
ERP Qhov Zoo Radiated Fais Fab yog tag nrho lub zog hluav taws xob los ntawm tus kav hlau txais xov tiag tiag txheeb ze rau ib nrab-yoj dipole es tsis yog lub kav hlau txais xov isotropic theoretical. Ib nrab-yoj dipole muaj qhov nce ntawm 2.15 dB piv rau tus kav hlau txais xov isotropic. Kev sib raug zoo nruab nrab ntawm EIRP thiab ERP tuaj yeem pom hauv kev sib npaug hauv qab no: Upvote.
EIRP txwv yog dab tsi?
Piv txwv li yog tias koj lub cev tswj hwm (FCC hauv Asmeskas, IC hauv Canada) tau teeb tsa qhov siab tshaj plaws EIRP (sib npaug isotropically radiated hwj chim) rau ib tug point-to-multipoint (PtMP) system rau 36 dBm nyob rau hauv lub 2.4 GHz band, koj tx zog ntxiv kav hlau txais xov nce yuav tsum tsawg dua los yog sib npaug rau 36 dBm.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
