Ntau yam yog qhov sib txawv ntawm qhov qis tshaj (tsawg kawg) thiab siab tshaj (qhov siab tshaj) qhov tseem ceeb. Nyob rau hauv cov ntaub ntawv no teem lub ntau yuav yog tus nqi siab tshaj rho tus nqi qis tshaj. Qhov siab tshaj (tus nqi siab tshaj) yog 10, qhov qis tshaj (tus nqi qis tshaj) yog 1. Yog li qhov ntau ntawm cov ntaub ntawv teev yog 9.
Ib yam li ntawd, koj yuav pom qhov ncua sij hawm ntawm lub rooj zaus li cas?
Ib lub rooj zaus rau cov ntaub ntawv uas muaj ntau tus nqi ntawm cov ntaub ntawv yog tsim raws li hauv qab no:
- Txiav txim siab cov ntaub ntawv ntau ntawm cov ntaub ntawv teev.
- Txiav txim siab qhov dav ntawm cov chav kawm ib ntus.
- Faib qhov ntau los ntawm kev xaiv dav ntawm chav kawm ntu ntu los txiav txim seb muaj pes tsawg lub sijhawm.
koj xam qhov ntau npaum li cas? Summary: Lub ntau ntawm ib txheej ntawm cov ntaub ntawv yog qhov sib txawv ntawm qhov siab tshaj thiab qis tshaj qhov tseem ceeb hauv cov txheej txheem. Rau nrhiav cov ntau , thawj xaj cov ntaub ntawv los ntawm tsawg kawg rau loj tshaj. Tom qab ntawd rho tus nqi tsawg tshaj plaws los ntawm tus nqi loj tshaj plaws hauv cov teeb.
Ib tug kuj yuav nug, dab tsi yog tus qauv rau ntau?
Txhua yam peb yuav tsum tau ua yog nrhiav qhov sib txawv ntawm cov ntaub ntawv loj tshaj plaws hauv peb lub teeb thiab cov ntaub ntawv tsawg tshaj plaws. Hais succinctly peb muaj cov hauv qab no qauv : Ntau yam = Tus nqi siab tshaj – Tus nqi tsawg kawg nkaus. Piv txwv li, cov ntaub ntawv teev 4, 6, 10, 15, 18 muaj qhov siab tshaj plaws ntawm 18, yam tsawg kawg ntawm 4 thiab ib qho ntau 18-4 = 14.
Yuav ua li cas koj pom qhov ntau ntawm cov histogram?
Suav cov ntaub ntawv cov ntsiab lus (50 hauv peb qhov siab piv txwv ). Txiav txim siab qhov ntau ntawm cov qauv - qhov sib txawv ntawm qhov siab tshaj plaws thiab qis tshaj qhov tseem ceeb (73.1-65, lossis 8.1 ntiv tes hauv peb qhov siab piv txwv . Txiav txim seb muaj pes tsawg lub sijhawm ntawm chav kawm.

Kuv yuav luam ib lub rooj los ntawm ib lub rooj mus rau lwm qhov hauv MySQL li cas?
MySQL muab qhov kev xaiv muaj zog rau kev luam cov ntaub ntawv los ntawm ib lub rooj mus rau lwm lub rooj (lossis ntau lub rooj). Cov lus txib yooj yim hu ua INSERT SELECT. Ib daim ntawv qhia tag nrho ntawm cov syntax yog qhia hauv qab no: INSERT [IGNORE] [INTO] table_name. [(column_name,)] Xaiv los ntawm table_name qhov twg
Dab tsi yog qhov tsis zoo ntawm kev faib ntau zaus multiplexing?
Qhov tsis zoo ntawm FDM Txhua qhov kev faib ntau zaus ntau cov channel tau txais kev cuam tshuam vim qhov dav dav fading. Yuav tsum muaj ntau tus modulators thiab cov ntxaij lim dej. Cov channel kev sib txuas lus yuav tsum muaj ib tug loj bandwidth. Qhov sib faib zaus multiplexing raug kev txom nyem los ntawm qhov teeb meem ntawm crosstalk
