AM demodulators yog siv nyob rau hauv ib qho ntawm cov khoom siv xov tooj cuauas yog siv rau AM tshaj tawm kev txais tos lossis xov tooj cua sib txuas lus uas siv amplitude modulation. Txawm hais tias amplitude modulation tsis yog siv dav raws li nws tau ntau xyoo dhau los, nws tseem siv rau kev tshaj tawm hauv Cov Ntev, Nruab Nrab thiab luv Wave bands.

Lub hom phiaj ntawm demodulator yog dab tsi?

Demodulation. Cov txheej txheem ntawm kev cais cov thawj cov ntaub ntawv lossis SIGNAL los ntawm MODULATED CARRIER Nyob rau hauv rooj plaub ntawm AMPLITUDE lossis FREQUENCY MODULATION nws suav nrog cov cuab yeej, hu ua demodulator lossis ntes, uas ua rau lub teeb liab sib cuam tshuam rau lub sijhawm tam sim no. Kev hloov pauv hauv amplitude lossis zaus, feem.

Cov khoom siv twg peb tau siv rau AM demodulation?

A diode detector yog cov khoom siv yooj yim tshaj plaws siv rau AM demodulation. Lub diode ntes tau tsim nrog lub diode thiab ob peb lwm yam.

Dab tsi demodulator siv rau FM?

Lub ntsuas ntsuas plaubyog tej zaum yog ib qho siv dav tshaj FM demodulator. Nws siv ib theem-hloov Circuit Court los tsim ib theem hloov ntawm 90 ° ntawm lub unmodulated carrier zaus. Qhov ntsuas no feem ntau yog siv hauv TV demodulation thiab siv hauv qee lub xov tooj cua FM.

Qhov twg yog lub ntsuas ntsuas feem ntau siv?

Lub diode ntes yog daim ntawv yooj yim ntawm kev ntes lossis demodulator siv rau AM demodulation - nws pom lub hnab ntawv AM teeb liab. Lub diode ntes yog qhov yooj yim tshaj plaws thiab yooj yim tshaj plaws ntawm amplitude modulation, AM teeb liab ntes thiab nws ntes lub hnab ntawv ntawm AM teeb liab.
