Kusho ukuthini ukuthi "16-bit" lapho kubhekiselwa kumsindo wedijithali?
Context:Isignali ye-PCM iwukulandelana kwamasampula omsindo wedijithali aqukethe idatha enikeza ulwazi oludingekayo ukuze kwakhiwe kabusha isignali ye-analog yangempela. Isampula ngalinye limelela ububanzi besignali ngesikhathi esithile, futhi amasampula ahlukaniswe ngokulinganayo ngesikhathi. I-amplitude yilona lwazi kuphela olugcinwe ngokucacile kusampula, futhi ngokuvamile lugcinwa njengenombolo ephelele noma inombolo ye-floating point, efakwe njengenombolo kanambambili enenombolo engaguquki yamadijithi: ukujula kwebhithi lesampula, okubuye kubhekiselwe kukho njengobude begama noma usayizi wegama.  I-resolution ibonisa inani lamagugu ahlukene angamelwa ebangeni lamagugu e-analog. Isinqumo sezinombolo eziphelele kanambambili sikhula ngokuphindaphindiwe njengoba ubude begama bukhula. Ukungeza i-bit eyodwa kuphinda kabili isinqumo, ukungeza ezimbili kuphindaphindwe kane njalo njalo. Inani lezilinganiso ezingaba khona ezingamelwa ukujula kwe-bit kwenani eliphelele lingabalwa ngokusebenzisa u-2 ^ n, lapho n ukujula kwe-bit. Ngakho-ke, uhlelo olunezinhlamvu ezingu-16 lunezincazelo ezingu-65,536 (2^16) ezingaba khona.
Ukuguqula umsindo ube ifomethi yedijithali kudinga ukuthatha amasampula omsindo wokuqala ngezikhathi ezithile. La masampula amelela amandla, noma ububanzi, begagasi le-analog njengoba lishintsha ngokuhamba kwesikhathi. Ukuze uthole umsindo wedijithali, lezi zinombolo zibhalwa nge-binary notation. Lapho umsindo wedijithali ukhangiswa njengama- 16-bit, sisuke sisho ukuthi amasampula amanani okuqoshwa komculi aqoshwa njengamanani kanambambili anezinombolo ezingu-16.
