Muri elegitoroniki, guhuza tekinoroji igezweho no gushushanya neza ni ngombwa.Abaterankunga babiri b'ingenzi muri uyu murima ni pulse code modulasiyo (PCM) hamwe n'imbaho zicapye (PCB).PCM na PCB bikoreshwa cyane mubikoresho bya elegitoroniki bitandukanye, kandi buriwese afite ibyiza n'ibiranga.Muri iyi blog, tuzatandukanya itandukaniro nubushobozi bwa PCMs na PCBs kugirango tumenye amahitamo meza kubyo ukeneye.
PCM (Pulse Code Modulation):
Pulse Code Modulation nuburyo bwa digitale yo kwerekana ibimenyetso bisa.Ihindura ibimenyetso bisa muburyo bwa digitale kandi ikoreshwa cyane mubikorwa byamajwi nko gufata amajwi no gutunganya umuziki.PCM buri gihe ifata amplitude ya buri sample yikimenyetso cyikigereranyo kandi ikagaragaza muburyo bwa digitale.Ubu buryo bwo gutoranya bwerekana neza ibimenyetso byumwimerere.PCM itanga amajwi meza cyane kandi azwiho ubudahemuka buhanitse, bigatuma biba byiza mugushushanya sisitemu y amajwi nibikoresho bisaba amajwi atavogerwa.
PCB (Icapa ryumuzingo wacapwe):
Ikibaho cyumuzingo cyacapwe nifatiro ryibikoresho bya elegitoroniki, bitanga urubuga rwo guhuza ibice bitandukanye.PCB igizwe n'inzira ziyobora zashizwe mumashanyarazi adafite imiyoboro kugirango itange amashanyarazi hamwe nubufasha bwibikoresho.PCBs yorohereza gahunda no guhuza ibice bitandukanye bya elegitoronike nka résistoriste, capacator na microchips.Ihinduka ryimiterere ya PCB ituma gahunda yumuzunguruko igoye, bigatuma ikoreshwa cyane mubikorwa bitandukanye nkitumanaho, icyogajuru, hamwe nibikoresho bya elegitoroniki.
Gutandukanya ibintu:
1. Imikorere:
PCM yibanda cyane cyane kubitunganya amajwi yerekana amajwi kugirango itange amajwi meza.Kurundi ruhande, PCBs igira uruhare mubikorwa rusange byibikoresho bya elegitoronike, byorohereza guhuza ibice bitandukanye no gutanga ituze kuri sisitemu.Mugihe PCM ari igice cyingenzi muri sisitemu yijwi, PCB ikoreshwa mubikoresho hafi ya byose bya elegitoronike, kuva kuri terefone zigendanwa kugeza kubikoresho byubuvuzi.
2. Igishushanyo mbonera:
PCM ikubiyemo ahanini algorithm ya software hamwe nubuhanga buhanitse bwo gutunganya ibimenyetso.Mugihe bisaba ubuhanga mubuhanga bwamajwi nubuhanga bwo gutangiza porogaramu kugirango hongerwe imikorere, biroroshye cyane mubijyanye nigishushanyo mbonera.Ibinyuranye, igishushanyo cya PCB gisaba gutegura neza imiterere, gushyira ibice, no gusesengura amashanyarazi.Irasaba ubumenyi bwamashanyarazi nuburyo bwiza bwo gushushanya kugirango ugere kumikorere wifuza.
3. Guhindagurika:
PCM yagenewe byumwihariko porogaramu zikoresha amajwi kugirango zemeze amajwi neza kandi zigabanye kugoreka.Intego nyamukuru yacyo nukuzigama ubusugire bwikimenyetso cyamajwi murwego rwa digitale.Kurundi ruhande, PCB ntabwo zigarukira gusa mubikorwa cyangwa inganda runaka.Guhindura kwabo kubemerera guhindurwa kugirango bahuze ibisabwa nigikoresho icyo aricyo cyose cya elegitoroniki, cyaba icyuma cyumuziki kigendanwa cyangwa sisitemu yo gutumanaho.
mu gusoza:
PCMs na PCB zombi ni abaterankunga b'ingenzi mu bijyanye na elegitoroniki, buri wese akora intego yihariye.PCM niyo ihitamo ryambere ryaba injeniyeri y amajwi na audiofile kubwiza bwamajwi butagira amakemwa.PCBs nizo shingiro zubatswe kuri sisitemu ya elegitoroniki igoye, itanga umurongo uhuza kandi uhamye.Nubwo PCM na PCB zitandukanye mubikorwa no mubishushanyo, akenshi bikoreshwa hamwe mubikoresho bya elegitoronike, bihuza imbaraga zidasanzwe.
Kurangiza, iramanuka kubisabwa byihariye byumushinga wawe cyangwa ibikoresho.Gusobanukirwa itandukaniro nibiranga PCM na PCBs bizagufasha gufata icyemezo cyuzuye ukurikije ibyo ukeneye.Niba rero wubaka sisitemu ya hi-fi cyangwa ugakora ibikoresho bya elegitoroniki byinshi, PCM na PCB nibikoresho byingenzi byo guteza imbere ikoranabuhanga.
