Redhiyo zano: pamusoro Chip uye iri nyore detector

Nyaya ino ichaongorora redhiyo redunhu, iro kuongorora basa nyore mazano. Imi mose munoziva kuti pane dzakawanda wavebands. Uye vose vari akakamurwa nhepfenyuro kuti Mobile, nokuti mukuru kushandiswa, uye mudzidzi redhiyo. Broadcasting nenhepfenyuro yakaitwa muna mid-siyana (AM, DM), refu (LW, LW), VHF (FM, iyo FM) mafungu. Zvino uchadzidza sei kuita mudziyo uri nyore kuti pakugamuchira redhiyo.

The detector redhiyo

avake ichi pave ose kutanga nhepfenyuro mudzidzi. Uye nemhaka kuzviunganidza, kunyange mwana, sezvo pasina hombe. Nokuti mukugadzira, unofanira kuwana zvinotevera zvinhu:

1. A shanduka capacitor.
2. Ndakamira pamusoro capacitor 4700 PF.
3. Pamahedhifoni ane Coil nemishonga ine 1500 ohms. Ko tani-2 vakakwana.
4. Semiconductor nesilicon diode mhando D9. Zvisinei, unogona kushandisa mukuru zvakare ano.
5. Copper waya uye mandrel dhayamita dzinenge 40 mm.

The pamusoro redhiyo schematic dhayagiramu kunobatsira kunzwisisa sei kuti tiite zvose kubatana zvinhu. Cherechedzai inofanira kubhadharwa kuti pamasikiro kanyanga, pasi, inductors. Of zvinhu izvi anofanira kukurukurwa yoga. The detector weredhiyo anogona kushanda vari kuwanda svikiro uye refu mafungu, saka unoda uzere dhishi nokuda kwayo kushanda.

kanyanga design, pasi uye coils

To redhiyo nematunhu munyaya vaishanda kuwanda MW, LW, Zvakanaka hf, zvinokosha kugadzira ari kanyanga. Zvinonzi zvakagadzirwa waya chidimbu. Unogona kushandisa multi-makirisito kuputira, chinhu chikuru kuti yaiva-chikamu pamuchinjikwa zvinopfuura 0.75 ba. mm. Asi akanyanya mafuta haafaniri kushandiswa. Kureba kanyanga Web ichaongororwa inobva kakawanda panguva iyo mugamuchiri achaita basa. dandemutande pakureba inofanira vakawanda kakawanda kukosha, chinoratidzwa mamita. Kana tiri kutaura pamusoro zvakawanda mamita 90 (3200 kHz), nokureba kanyanga zvinofanira M kanenge 10. Zvinofanira umbomiswa panguva nekukwirira kanenge 3 metres uye kunyatsoongorora putira, masvingo miti uye nematanda.

Sezvo pasi anogona kushandisa kudziyisa nenyere. Zvisinei, akakodzera sarudzo yaizova simbi mbambo nomuzvanza kamwe mita muvhu. The coils iri muchikuvadza nemhangura waya chete. Uyezve, tinofanira kuva munhu ukobvu kwazvo 0.75 neMM, kuti simba unogona kuita zvaaitaura. The coils iri muchikuvadza pamusoro mandrel hwakasimba kunoguma makachengeteka pei. Tapota cherechedza kuti unoda zvishoma pamusoro 90 Anoshandura mhepo, saka edza kudimburira munhu mandrel kwenguva yakareba sezvingabvira. Izvi Zvirongwa maredhiyo zvakanaka chete nokuti vanogona kunzwisisa kwomudzimu kwakadaro mano. Asi ayo utetsa yakaderera zvikuru, saka rinogona kushandiswa kuteerera simba chete yeredhiyo. Kunyange kubatana kuti zvokunze gudzazwi bass uchaponesa.

Radio pamusoro Chip

Kumusoro redhiyo redunhu riri Chip K174HA34. Ichi chinhu chiduku yaunganidzwa akawanda nodes - detector, mumwe kakawanda convert chiratidzo gudzazwi. Chokwadi, Chip ichi yechinyakare, asi vachiri yakabereka, uye rinodhura yakaderera chaizvo. Chiizve chinodiwa kuti kutanga Wireless Zvokutopenga? Kana kunyange Anotadzira chinhu, haisi tsitsi. Kunewo dzomuzana vatorwa, vachibvumira kubereka maredhiyo kuti VHF, uye mutengo wavo haisi guru chaizvo. zano Izvi zvakanaka nokuti haaiti chishoma okunze, asi unogona kugamuchira nenhepfenyuro Mukutepfenyura siyana. Imwe drawback - kudiwa kuita mamwe gudzazwi yakaderera kakawanda, sezvo goho redunhu rimwe simba chaizvo chiratidzo.

mhedziso

Shoma kunzwisisa pamwe redhiyo design, anogona mberi kusvika zvaAtemisi yakawanda dzakaoma mano. Modern zvemagetsi zvinoriumba kunoita kuti iwe kwete chete vagamuchiri, amplifiers, uye zvinotakura asi kuti richava rinokosha panguva yezororo zvakasikwa, kuti vaite basa rokuvaka, uyewo kudzora motokari. Somuenzaniso, nokuti Implementation ari otomatiki kutanga. Nemamwe mashoko, redhiyo redunhu zvakadaro dzichipfekeka kuti anoshandiswa kwose kwose nhasi.
