Microphone yokukhulisa umsindo: isikimu. Microphone amplifier for umbhobho electret

I-microphone amplifier - idivaysi kwandisa isignali conductivity. Kuncike inqubo ababhidisi wathi. Imodeli ejwayelekile kuhlanganisa capacitors, futhi thyristors. Modulators, yokukhulisa umsindo afakiwe e izinhlobo ezahlukene.

Ukuze kwandiswe ukuzwela babashayeli esetshenziswa tetrode. Wegazi ezifakiwe umthamo ezahlukene. Ukuze silondoloze zinamandla esitebeleni contactors asetshenziswa circuit. Ukuze uthole olunye ulwazi mayelana amadivaysi, kufanele ucabangele uhlobo oluthile umbhobho yokukhulisa umsindo.

Single nalevulekile uhlelo ukuguqulwa

Single-yaphela umbhobho yokukhulisa umsindo (scheme kukhonjisiwe ngezansi) zenziwa ngesisekelo wire capacitors. Kulokhu, isiginali inhlamvu ikhethwa nge conductivity eliphezulu. onobuhle abaningi basebenzisa resistors ezimbili. Uma sicabangela ongaphakeme kudivayisi amandla ke efakwe isihlungi esisodwa.

Thyristors esetshenziswa ngqo ngaphandle umhlahlandlela. Transceivers babe onobuhle isethelwe Wegazi. Inkomba okukhipha kubhedere emhlabeni 4.5 mV. Kulokhu, lo voltage embundwini ingeqi 10 V. Inkomba sindisa zamanje incike conductivity we olwandisa.

Model push-silingo uhlobo

I-push-silingo amplifier chip capacitors enziwe emkhakheni. Wegazi asetshenziselwa onobuhle letingemasayizi lahlukene. Ngokuvamile, ukuzwela ekhishwa ipharamitha lingaphansi kuka 5 mV. Kulokhu, flip-flops asetshenziswa ngaphandle babashayeli.

Ngokwesilinganiso, voltage embundwini ku insulators kuyinto 12 V Yenza lolu hlobo umbhobho amplifier ngezandla zakho kalula. Ukuze wenze lokhu, akhethiwe PP20 uchungechunge chip. Ngqo extender kudingeka ephethe namandla esifundeni 6 PF. Futhi nge capacitors efakwe SCR. isignali conduction kuleli cala kudingeke ukuba kungabi ngaphansi kuka 2.2 microns.

Iinsetjenziswa amplifier trehtaktnogo

Trehtaktnye umbhobho yokukhulisa umsindo (scheme kukhonjisiwe ngezansi) aqukethe capacitors ensimini. Sekukonke, idivayisi sinezibangeli ezimbili. Inkomba okukhipha inzuzo ilingana 5.8 mV. Kulokhu, lo dilators asetshenziselwa 2 PF. Contactors ngqo ukukhwezwa nge insulators.

Uma kudingekile, ungakwazi ukuqoqa msindo umbhobho ngezandla zakho. Ngenxa yalesi chip lokuqala luthatha uhlobo multi-umzila. Futhi, amplifier Uzodinga olwandisa ephethe namandla mayelana 2.3 PF. Uma sicabangela imodeli elula, lemifanekiso ovunyelwe ukusebenzisa uhlobo umswakama. overcurrent sepharamitha ngokwesilinganiso kufanele kube kungekho kuka 6 A.

Indlela yokwenza umfuziselo emitter ezivamile ngezandla zakhe

Microphone amplifier (scheme kukhonjisiwe ngezansi) nge emitter ezivamile kwakhiwa ngesisekelo emkhakheni capacitors. Resistors zisetshenziswa kanye conductivity eliphezulu ipharamitha. Endaweni yokuqala ukwakha thyristor ukuvunwa. Faka ezilandelayo inhlamvu. Inkomba okukhipha isici ukuzwela kumelwe ibe ngaphansi 6.5 mV. Ngakwelinye ihlangothi, ukulungiselelwa overcurrent liyadingeka ulingana 8 A. contactor ebhodini isethwe eduze zokuhlunga.

Idivayisi nge ngalendoda

Yokukhulisa umsindo nge ngalendoda efanelekayo studio imibhobho ngokufanele. Capacitors asetshenziswa amamodeli we ishayela hlobo. wesifunda Ubude has resistors ezintathu. Sepharamitha okukhipha inzuzo, ngokwesilinganiso elilingana 5.6 mV. Kulokhu inhlamvu enamadijithi-ezintathu noma zamadijithi amabili uhlobo. Uma sicabangela samuntu lokuqala, extender kuyakhethwa capacitance 5 PF.

I thyristor isetshenziswa ne contactors. Transceivers zitholakala ngqo eduze capacitor. Okuncane okukhipha voltage kuyinto 12 V. Uma sicabangela busebenze nge enamadijithi amathathu-trigger, le extender isetshenziswa ephethe namandla angaphezu kuka 5 PF. Capacitors ezifakiwe Vector uhlobo kuphela. Inani imodeli kuzodinga modulators ezintathu. Okuncane okukhipha voltage kuyinto 15 V. izihlungi zisetshenziselwa ekulinganiseni zamanje embundwini.

Amadivayisi nge AGC (automatic control inzuzo)

AGC amplifier muva nje zithandwa kakhulu. Okokuqala, bona zinezikhathi low power ukusetshenziswa. Tetrodes amamodeli zisetshenziswa oxhumana ezimbili. Uma sicabanga elula amplifier wesifunda, lemifanekiso isethelwe lo thyristor. Umthamo olwandisa liyadingeka kungabi ngaphansi kuka 8 PF. Inkomba okukhipha kubhedere ecishe ilingane 4.5 mV. Kulokhu, lo mshini wokukhulisa umsindo umbhobho nge AGC angase ufake capacitors evulekile-hlobo. Inani imodeli kuzodinga ezintathu Transistor scalar. Wegazi, imodeli setha ngendlela ezilandelanayo.

Models studio imibhobho Canyon

Ukuze studio umbhobho amplifier onobuhle (scheme kukhonjisiwe ngezansi) akhiqizwa ngesisekelo a modulator ishayela. Ubude ayengasetshenziswa inhlangano edingekayo transceivers ezimbili. Capacitors asetshenziswa nge okukhipha contactor. Ubuncane okukhipha ukuzwela kuyinto 2 mV. Kulokhu, inhlamvu kungenzeka insulators esetshenziswa ngokukhululekile. Lemifanekiso efakwe ukumuncwa hlobo. Isilinganiso embundwini voltage we yokukhulisa umsindo yalolu hlobo kuyinto 12 V

Models epholisayo imibhobho "Umdlali wasemuva"

Zesikhulisa chip for epholisayo imibhobho siqukethe emkhakheni resistors. Ukuze axazulule izinkinga nge isignali kokuqhuba isicelo ugongolo tetrode. Kulokhu, flip-flops asetshenziswa njengoba uhlobo pulsed nokusebenza. Modulators ezifakiwe nge conductivity ongaphakeme. Sepharamitha okukhipha inzuzo ilingana hhayi ningi than 5 mV. Enhancers kulokhu kuvunyelwe ukuba kusetshenziswe namandla 4.2 PF. Amamodeli nge Wegazi chromatique awavamile.

Zesikhulisa Microphone uhlobo electret "Sven"

Microphone amplifier for umbhobho electret akhiwa ngesisekelo capacitors feedthrough. Esikhathini isikimu esezingeni idivayisi inakho resistors ezintathu. Basuke efakwe ukuze ezilandelanayo. isignali conduction izinga labo zilingane microns mayelana 8. Kulokhu, ipharamitha okukhipha ukuzwela liyashintshashintsha emhlabeni 3.3 mV. Thyristors ku-msindo umbhobho i-microphone electret akhethiwe ngaphandle contactors. Ashaywe avame ukusetshenziswa ongaphakeme-imvamisa hlobo. Eceleni ukuhlunga le tetrode. I olwandisa kufanelekile onobuhle ephethe namandla amancane. Modulators ngokuvamile efakwe ngemuva inhlamvu.

Isibonelo Esperanza imibhobho

Yokukhulisa umsindo ukuze lemibhobho ekhiqizwa eyodwa-isenzo hlobo. Capacitors asetshenziswa imodeli ensimini. Resistors ngokuvamile efakwe nge contactors. Sekukonke, zikhona ezintathu iphethini olwandisa. Umthamo inkomba zabo zilingana 4.5 PF. Kulokhu, ukuzwela okukhipha ezingekho ngaphezu 8 mV. Ashaywe amadivayisi akhethiwe contact ezintathu.

Sepharamitha ubuncane embundwini voltage kuyinto 12 V. Izihlungi kuphela efanelekayo amadivaysi ukumuncwa hlobo. Balindeleke ukuba bakwazi ukufakwa eduze modulator. Ngokushesha contactors asetshenziswa izicelo nge ongaphakeme isignali-Umqhubi. Ngenxa yale nkinga zingaxazululwa nge polarity ezimbi.

Idivayisi imibhobho Trust

Microphone amplifier ku-chip zalolu hlobo locingo yakhiwa ngesisekelo capacitors feedthrough. Ubude yedivayisi kuzodinga resistors ezimbili. Kufanele ukufakwa kanye izihlungi. Self-inhlangano edingekayo extender amplifier. Ochwepheshe abaningi bakholelwa ukuthi ukumelana esiphezulu kule wesifunda ubophekile ukuba ohms 50.

Kulokhu, inhlamvu akuyona okweqile kakhulu. Contactors Site imodeli evulekile. Kwezinye izimo, yokukhulisa umsindo aqukethe trigger zamadijithi amabili okungasenani.
