Baseband modulation: Nws yog ib hom demodulator. Hauv kev sib txuas lus thiab kev sib txuas lus, lub ntsiab lus ntawm bandwidth txawv ntawm cov ntsiab lus saum toj no. Nws yog hais txog qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov qis tshaj plaws uas tuaj yeem siv los ntawm cov teeb liab network, lossis qhov dav ntawm cov zaus band. , uas yog lub npe hu ua channel bandwidth, uas tseem yog cov lus qhia nruj tshaj plaws.
Xov tooj cua Frequency Modulation: Modulator yog cov ntawv luv ntawm cov khoom siv zaus uas nyob ib sab, feem ntau hu ua xov tooj cua zaus modulator lossis TV modulator, uas yog ib qho ntawm cov cuab yeej tseem ceeb hauv chav cable TV pem hauv ntej-kawg computer.
Qhov txawv ntawm ob:
1. Kev ua haujlwm sib txawv: baseband modulation yog hais txog lub network broadband thiab xov tooj cua zaus hloov kho TV modulators.
2. Cov khoom siv modulation yog txawv: lub hauv paus kev hloov pauv yog rau lub network, thiab lub xov tooj cua zaus hloov kho yog rau TV.
