Ratidza chiyero chemuenzaniso: Zvese zvaunoda kuziva

Munyika yemafoni emafoni, chimwe chezvinhu zvakakosha kuratidzwa kwayo. Pamusoro pekutarisa rudzi, saizi, resolution, kupenya kwakanyanya, color gamut uye pamwe kunyangwe kusiyanisa, mwero wekuzorodza wakakurukurwawo zvakanyanya mumakore achangopfuura. Kubva pachiyero che60Hz, isu tave kutotanga kuenda ku120Hz paPhones, uye izvo zvakare zvinochinjika. Asi kunze kweyero yekuzorodza, kune zvakare chiyero chesampling. Zvinorevei chaizvoizvo? 

Sample rate inotsanangura nhamba yenguva iyo skrini yemudziyo inogona kunyoresa kubata kwemushandisi. Kumhanya uku kunowanzoyerwa musekondi imwe uye kuyerwa kweHertz kana Hz kunoshandiswawo kuratidza frequency. Kunyangwe chiyero chekuzorodza uye chiyero chemuenzaniso chinonzwika zvakafanana, chokwadi ndechekuti ivo vese vanochengeta zvinhu zvakasiyana.

Kaviri 

Nepo mwero wekuzorodza uchireva izvo izvo skrini inogadziridza pasekondi pachiyero chakapihwa, chiyero chemuenzaniso, kune rumwe rutivi, chinoreva kuti kazhinji sei skrini "inonzwa" uye inorekodha kubata kwemushandisi. Saka sampling rate ye120 Hz zvinoreva kuti sekondi yega yega skrini inotarisa vashandisi kubata ka120. Muchiitiko ichi, chiratidziro chinotarisa yega 8,33 milliseconds kuti uri kuibata here kana kuti kwete. Mwero wepamusoro wesampling zvakare unokonzeresa mushandisi anoteera kusangana nenharaunda.

Kazhinji, sampling frequency inofanira kunge yakapetwa kaviri chiyero chekuzorodza kuitira kuti mushandisi asaone chero kunonoka. MaPhones ane 60Hz yekumutsiridza chiyero saka ane sampling rate ye120 Hz, kana iyo iPhone 13 Pro (Max) ine yakanyanya kuzorodza mwero we120 Hz, chiyero chesampling chinofanira kunge chiri 240 Hz. Nekudaro, iyo sampling frequency zvakare inotsamira pane mudziyo chip inoshandiswa, iyo inoongorora izvi. Inofanirwa kuona nzvimbo yekubata kwako mukati me milliseconds, woiongorora uye woidzosera kune chiitiko chauri kuita izvozvi - kuti pasave nekunonoka kuita, izvi zvakakosha kana uchitamba mitambo inoda.

Musika mamiriro 

Kazhinji, zvinogona kutaurwa kuti kune vashandisi vanoda yakanakisa uye yakatsetseka ruzivo vachishandisa mudziyo, kwete chete chiyero chekuzorodza chakakosha, asiwo chiyero chesampling. Mukuwedzera, inogona kuva yakakwirira kudarika kaviri chete. E.g. iyo yemitambo ROG Runhare 5 inopa sampling frequency ye300 Hz, iyo Realme GT Neo inosvika 360 Hz, nepo Legion Runhare Duel 2 kunyange kusvika 720 Hz. Kuisa izvi mune imwe maonero, chiyero chekubata chiyero che300Hz chingareva kuti chiratidziro chagadzirira kugamuchira yekubata pese 3,33ms, 360Hz yega 2,78ms, ukuwo 720Hz ipapo yega yega 1,38ms.
