Kutsitsa Kutsitsa ndi chimodzi mwa zinthu zazikulu za radio

M'makonzedwe amasiku ano, kusintha kwakukulu kwa kusagwira kwapezeka kwakukulu. Njira yaikulu ya zinthu zoterezi ndi kukana magetsi. Kwa makhalidwe achiwiri a ziwalo zoterezi, wina akhoza kuphatikizapo kutaya kwa mphamvu yamtunduwu ndi zolakwika muzitsulo zolimbana nazo. Malingana ndi kuthekera kwa kusintha kusakanikirana, kusiyanitsa pakati pa zida zowonongeka zowonongeka za mtundu uwu. Mtundu woyamba wa chinthu ichi umatsutsa, womwe sungasinthe. Pachifukwachi, mawonekedwe achiwiri a chinthu choterocho akhoza kusintha khalidweli. Mbali iyi ya zigawo zimaphatikizapo zowonjezereka, zowonjezera, zosinthika komanso zosakaniza. Mayi awiri oyambirira amagwiritsidwa ntchito kwambiri pa zamagetsi, zomwe zimagwiritsidwa ntchito nthawi zambiri mumagetsi.

Pogwiritsa ntchito mapangidwe, kusakanikirana ndi kusungunula kwake kumagawidwa mu waya ndi opanda waya. Malingana ndi njira yosinthira kukana, kusiyanitsa pakati pa rotary ndi slider.

Chophweka chophweka cha kutsutsana kwa waya. Monga maziko, ali ndi mphete ya dielectric. Foni iyi imayendayenda pamtunda, kumapeto kwake komwe kumagwirizanitsidwa ndi 2 nd terminal othandizira a radiyo element. Chida chogwiritsira ntchito ndi chojambulidwa pamwamba (chiyenera kugwirizanitsa ndi mpheteyo) ndi chivundikiro chokhala ndi phokoso lozungulira ndi chofufumitsa chaikidwa pa icho. Pa sitepe yotsatira, chiyanjano chapakati chimakhazikitsidwa, chomwe chimagwirizanitsa chigawo chachikulu ndi membala woyendayenda. Gawo lotsiriza la kupanga chigawo chimodzi cha wailesi ngati kupewera kugwiritsira ntchito ndiko kukhazikitsa dongosolo lomwe lasonkhanitsidwa mu vuto loteteza. Choncho tiwone mwachidule kayendedwe kachipangizo kogwiritsa ntchito zigawozi. Ngati gawoli ndilo la kalasi ya waya opanda waya, kuyendayenda kwa waya kumadumphira - mpheteyo siimapangidwa ndi dielectric, koma nthawi yomweyo kuchokera kuzinthu zomwe zimakhala zotsutsa (nthawi zambiri zimakhala zosawerengeka padziko lapansi). Mtengo wa zigawo zikuluzikulu zopangidwa motere ndi zazikulu kuposa poyamba, ndipo chifukwa cha ichi iwo sanaperekebe zambiri.

Chigawo ichi cha pakompyuta chapeza ntchito yaikulu pakukulitsa magawo (mothandizidwa ndi phindu loyendetsedwa ndilo). Pogwiritsa ntchito, kukana ndi kukaniza nthawi zonse kumaikidwa, ndipo pamtunduwu - ndi variable resistor. Pambuyo pomaliza msonkhano wa dera, ndi chithandizo cha chinthu chomaliza chomwe phindu lofunikira likusankhidwa. Kuti tichite izi, mphutsi imayenda mpaka momwe ntchito yofunirayo ikufunira. Ndondomekoyi itatha, varnish (pa resistor) iyenera kugwiritsidwa ntchito kuchokera pamwamba. Chigawo chogwiritsira ntchito chingathe kutembenuka mwachangu (kuchokera kukhudza, kuchoka ku kugwedeza, kugwa) ndiyeno nkofunika kusintha deralo kachiwiri. Pofuna kupewa izi, ndikugwiritsanso ntchito varnish pamwamba kuti mukonzekere kukanika.

Kuwona kufunika kwa gawo lochitidwa ndi nyamayi mu chipangizo chamakono cha microprocessor (osati kokha) kuli kovuta. Koma motsimikizika tikhoza kunena kuti chigawo chotere cha wailesi chikugwiritsidwa ntchito pafupifupi zipangizo zamagetsi zonse. Ndipo ndikukonzekera kutsutsana chaka chilichonse kupeza zambiri ndikugwiritsa ntchito njira zatsopano zothetsera dera.
