Ob-sideband suppressed-carrier kis tau tus mob (DSB-SC) yog kis tau tus mob nyob rau hauv uas zaus tsim los ntawm amplitude modulation (AM) yog symmetrically spaced saum toj no thiab qis dua tus cab kuj zaus thiab cov cab kuj theem yog txo rau qib qis tshaj qhov ua tau zoo, qhov zoo tshaj plaws raug tshem tawm tag nrho.

Vim li cas tus neeg nqa khoom raug tshem tawm hauv amplitude modulated nthwv dej?

Nyob rau hauv tus txheej txheem ntawm Amplitude Modulation, lub modulated yoj muaj cov cab kuj yoj thiab ob sidebands. … Yog tias tus neeg nqa khoom no raug txwv thiab lub zog txuag tau muab faib rau ob lub sidebands, cov txheej txheem no hu ua Double Sideband Suppressed Carrier system lossis tsuas yog DSBSC.

Kev tiv thaiv kab mob yog dab tsi?

: a txoj kev ntawm lub teeb liab kis tau tus mob uas lub zog cuam tshuam tseem ceeb nrog cov neeg nqa khoom zaus tsis kis.

Yuav ua li cas koj txwv cov neeg nqa khoom tsis xav tau hauv AM nthwv dej?

Ntsuas Modulator (Suppression of Carrier)

Cov khoom sib npaug yog siv los txhawm rau txwv tsis pub cov cab kuj tsis xav tau hauv AM yoj. Cov cab kuj thiab cov teeb liab modulating yog siv rau cov inputs ntawm lub balanced modulator thiab peb tau txais lub DSB teeb liab nrog supressed carrier ntawm cov zis ntawm lub balanced modulator.

DSBSC thiab SSB SC yog dab tsi?

DSB-SC vs SSB-SC | Qhov sib txawv ntawm DSB-SC thiab SSB-SC. … DSB-SC sawv cev rau Ob Chav SideBand Suppressed Carrier thiab SSB-SC sawv cev rau Ib leeg SideBand TxhaumTus neeg nqa khoom. Ob leeg ntawm no yog kev hloov kho techiques siv nyob rau hauv AM (Amplitude Modulated) zaus spectrum.
