Intaneti mbendera - quality, kudalirika, chitetezo

Modern mudziwe dziko kusiyana mofulumira kwambiri, kotero ine ayenera kuyesera kuti nthawi zonse kwa tsiku ndi umisiri watsopano. Izi adzalola inu kuchita kusintha ndi kulandira chithandizo wapamwamba kwambiri.

Pakuti munthu wamba mu msewu chikhalidwe cha digito kapena analogi mbendera - chodabwitsa ndi uninteresting. Koma pamene pali funso za kusiyana akamagwiritsa digito ndi analogi kapena chizindikiro, ayamba kumufunsa mafunso. Ndi palibe chinsinsi kuti umisiri kuti zimamangidwa pa mfundo za analogi, posapita nthawi, adzatha linakhalapo ndi kwathunthu kupereka impso wa kulanda mudziwe "chithunzi".

Koma mpaka pano siinafike, nthawi pali kufunika kuti atembenuke ndi analogi mbendera yadigito. Komanso si zachilendo, pamene kuli kofunikira kuti digito kwa analogi kutembenuka chizindikiro.

Mbendera analogi pakati pake penipeni - ichi ndi wapadera chizindikiro deta mtsinje, sipangakhalenso anafotokozedwa ndi zina ntchito mosalekeza za nthawi. Izi zikutanthauza kuti pa oscillation matalikidwe kungakhale phindu mu maxima ena.

Intaneti mbendera - wapadera chizindikiro deta mtsinje, sipangakhalenso anafotokozedwa ndi ntchito zina apawokha za nthawi. Kuti, matalikidwe ake zitha kutenga mtengo bwino chimatanthauza.

Kuti chizindikiro analogi yodziwika ndi ambiri kusokonezedwa osiyana. Mbendera digito ali mbali zothandiza zosefera ambiri kusokonezedwa angathe. Izi zimatheka mwa mphamvu kuti achire onse deta pachiyambi. Komanso, chizindikiro digito chimasiyanitsa pakalibe redundancy mudziwe deta mtsinje, pamene chifukwa analogue kutengerapo khalidwe opanda kuchuluka kwambiri kwa zamalankhulidwe katundu zambiri. Mu njira thupi angathe kupatsira chizindikiro angapo digito, pamene analogi chimodzi chokha.

Mbendera digito ali khalidwe lina lofunika - ndi moyo wake. Choncho, chizindikiro analogi umamumvera pafupifupi asatengere kapena kuwukira kwa chilengedwe. Pa nthawi yomweyo, kuti ali ndi mphamvu kuti digitally encrypted pouza izo kachidindo wapadera ku ya nyemba. Izi kumatha pafupifupi kusokonezedwa iliyonse ndi anthu amene alibe ufulu umenewu, mu ndondomeko ya kusintha deta. The sangathe ndi "manambala" - izi ndi zovuta za kufala pa mtunda wautali. Koma vutoli mosavuta anathana ndi kugwiritsa ntchito zipangizo zapadera kuti Kusinthasintha ntchito / demodulation.

The kusintha kwa mbendera digito kwambiri za ogwiritsa TV. Kwa anthu ambiri, TV anali ndi kukhala gwero yekha zambiri. Pa njira yomweyo chakale salandira "chithunzi". Choncho ndikofunikira ntchito chipangizo wapadera -preobrazovatel chizindikiro yadigito.

Ingakuthandizeni kutembenuza chizindikiro chilichonse digito mu analogi ankafuna. Izi amapewa zina ndalama kwa ogulidwa latsopano TV ndi limalola ntchito deta khalidwe digito pa chipangizo chanu analogi.
