Ukulawula okukude kwe-Universal (4 koku-1)

Iphutha 1: zonke izinkinobho kurimothi azisebenzi.

Ukuhlaziywa nokunakekelwa: iningi lezizathu zokuthi kungani zonke izinkinobho zesilawuli kude zingasebenzi zibangelwa ukulimala kwe-crystal oscillator. Uma uwile noma uhlolile nomsakazo ukuthi awukho umsindo we "beep", ungawufaka ngqo nge-crystal oscillator entsha. Ngemuva kokushintshwa kwe-crystal oscillator entsha, uma iphutha lisengasuswa, amandla wevolumu kuzo zombili iziphetho ze-crystal oscillator kufanele alinganiswe kuqala. Lapho noma yimuphi ukhiye ucindezelwe, kuzoba khona ukushintsha kwamandla okusobala emikhawulweni yomibili ye-crystal oscillator, ekhombisa ukuthi i-oscillator ingaveza isignali yokushaya kwenhliziyo. Okwesibili ukubheka ukuthi ngabe kukhona yini ukushintsha kwamandla okubuthakathaka ekugcineni kwesiginali yesilawuli kude se-block edidiyelwe. Uma kunoshintsho, hlola ukuthi ngabe i-triode yokushayela nethubhu yokudlulisa i-infrared kulimele yini. Ngaphandle kwalokho, iningi lamabhulokhi ahlanganisiwe anephutha.

Iphutha 2: ezinye izinkinobho azisebenzi.

Ukuhlaziywa nokunakekelwa: le nto ikhombisa ukuthi irimothi ijwayelekile yonke, futhi isizathu esenza ukuthi ezinye izinkinobho zingasebenzi ukuthi oxhumana naye wesekethe ukhiye akakwazi ukuqhuba kahle. Iningi loxhumana nabo ebhodini lesifunda kurimothi lingcolile, okwenza ukumelana koxhumana nabo kukhuphuke noma kungakwazi ukuxhunywa. Ukotini ofakwe otshwaleni ngokuphelele ungasetshenziselwa ukusula oxhumana nabo bekhabhoni, kepha hhayi kanzima kakhulu ukuvimbela ifilimu lekhabhoni ekugqokeni noma ekuweni. Ukuguga noma ukugqoka injoloba eqhubayo nakho kungadala ukuthi izibopho zomuntu ngamunye zingasebenzi. Ngalesi sikhathi, inqobo nje lapho iphuzu lokuxhumana lenjoloba eliqhubekekayo linamathiselwe ebhokisini likasikilidi (mhlawumbe i-aluminium foil adhesive) zama. Uma lezi zindlela ezingenhla zingakwazi ukwenza isilawuli kude sibuyele ekusebenzeni okujwayelekile, hlola ukuthi ngabe kukhona ukuxhumana okungaxakekile noma okungahambi kahle kusekethe kusukela ekufakweni kwesiginali se-keying nokuphela kokukhipha kuya endaweni yokuxhumana yebhlokhi elihlanganisiwe, ikakhulukazi ekuxhumaneni phakathi kwekhabhoni oxhumana naye ngefilimu nolayini wesifunda. Uma kunesidingo, buyisela ibhulokhi ehlanganisiwe.
