"16-bit" rinorevei parinenge richitaura nezvenzwi redhijitari?
Context:Chiratidzo chePCM chinotevedzana chezvinyorwa zvemazwi zvemasvomhu zvine dheta rinopa ruzivo rwakakosha kuvakazve chiratidzo chepakutanga cheanalog. Muenzaniso mumwe nomumwe unomiririra uwandu hwechiratidzo panguva yakatarwa munguva, uye mienzaniso yacho yakaenzana munguva. The amplitude ndiyo chete mashoko zvakajeka zvakachengetwa ari mharidzo, uye kazhinji zvakachengetwa sezvo kana munhu integer kana zvinoyangarara pfungwa nhamba, encoded somunhu binary nhamba pamwe yakatarwa nhamba digits: mharidzo wacho zvishoma kudzika, anonziwo shoko urefu kana shoko kukura.  Kugadziriswa kunoratidza nhamba yemitengo yakasarudzika inogona kumiririrwa pamusoro penzvimbo yemitengo yeanalog. Kugadziriswa kwenhamba dzakakwana mbiri kunowedzera zvikuru sezvo urefu hweshoko hunowedzera. Kuwedzera chimwe chiduku kunopeta kaviri chisarudzo chacho, kuwedzera zviviri kunopeta kane chacho uye zvichingodaro. Nhamba yezvinobvira zvingamiririrwa nehuwandu hwehuwandu hwehuwandu hunogona kuverengwa nekushandisa 2 ^ n, apo n ihwo hukuru hwehuwandu. Nokudaro, gadziriro ye 16-bit ine chisarudzo che 65,536 (2^16) mavara anobvira.
Kushandura inzwi kuva chinyorwa chedigital kunoda kutora mienzaniso yenzwi rokutanga nguva nenguva. Mienzaniso iyi inomiririra simba reanalogue wave, kana kuti amplitude, sezvainosiyana-siyana nokufamba kwenguva. Nokuda kwemashoko edhijitari, nhamba idzi dzakanyorwa muzviratidzo zvebhinari. Apo inzwi redhijitari rinoshambadzirwa se16-bit, tinoreva kuti mienzaniso yenhamba yokurekodha kwomuimbi yakanyorwa se16-digit-refu nhamba dzebhinari.
