Cov qauv yooj yim ntawm qhov chaw nres tsheb qhov rooj tej thaj chaw deb

Qhov kis ntawm ib feem ntawmqhov chaw nres tsheb qhov rooj tej thaj chaw debfeem ntau muab faib ua ob hom, uas yog, cov chaw taws teeb tswj(chaw nres tsheb qhov rooj tej thaj chaw deb)thiab transmission module. Cov chaw taws teeb tswj thiab cov chaw taws teeb tswj module yog rau hom kev siv. Cov chaw taws teeb tswj tuaj yeem siv nws tus kheej los ua lub tshuab ua tiav, thiab cov kab hluav taws xob sab nraud muaj cov kab hluav taws xob lub taub hau; Cov chaw taws teeb tswj module yog siv los ua ib feem hauv Circuit Court thiab siv raws li nws tus pin txhais. Qhov kom zoo dua ntawm kev siv cov chaw taws teeb tswj module yog tias nws tuaj yeem txuas seamlessly nrog daim ntawv thov Circuit Court, ntim me me, tus nqi qis thiab ua kom zoo tshaj plaws siv txhua yam. Txawm li cas los xij, tus neeg siv yuav tsum to taub tiag tiag lub hauv paus ntsiab lus ntawm Circuit Court. Txwv tsis pub, nws yog qhov yooj yim los siv cov chaw taws teeb tswj.

Feem ntau hais lus, qhov tau txais ib feem ntawmqhov chaw nres tsheb qhov rooj tej thaj chaw debkuj muab faib ua ob hom, uas yogsuper heterodyne chaw nres tsheb qhov rooj tej thaj chaw debthiab super regenerative txais homchaw nres tsheb qhov rooj tej thaj chaw deb. Lub super regenerative demodulation circuit tseem hu ua super regenerative detection circuit. Nyob rau hauv qhov tseeb, nws yog ib tug regenerative nrhiav kom tau Circuit Court ua hauj lwm nyob rau hauv lub intermittent oscillation xeev. Superheterodyne demodulation Circuit Court yog tib yam li xov tooj cua superheterodyne. Nws yog nruab nrog lub zos oscillation Circuit Court los tsim cov teeb liab oscillation. Tom qab sib xyaw nrog cov teeb liab tau txais cov khoom siv zaus, qhov nruab nrab zaus (feem ntau 465kHZ) tau txais. Tom qab nruab nrab zaus amplification thiab nrhiav kom tau, cov ntaub ntawv teeb liab yog demodulated. Vim hais tias cov cab kuj zaus raug kho, nws Circuit Court yog yooj yim dua li ntawm lub xov tooj cua. Tus txais superheterodyne muaj qhov zoo ntawm kev ruaj ntseg, siab rhiab heev thiab muaj peev xwm tiv thaiv kev cuam tshuam zoo; Super regenerative receiver yog me me thiab pheej yig. Yooj yim daws.
