Pokhudzana ndi kusunga chiyero, pali zinthu zosiyanasiyana zofunikira kuziganizira ndikuziganizira. Ngakhale kuti anthu ambiri amadziwika bwino, Intermodulation Distortion (yofotukulidwa monga IMD) ikhoza kukhala yovuta pamene imabweretsanso mutu wake woipa, wodabwitsa. Mosiyana ndi zosiyana ndi zosiyana ndi zina za nyimbo, Kusokonezeka kwa Intermodulation kumveka kwa khutu ndipo kungakhale chimodzi mwa zovuta kwambiri kuchepetsa machitidwe a audio.
Kodi Kusokoneza Maganizo N'kutani?
Kusokoneza maganizo pakati pa anthu nthawi zambiri kumapezeka ngati zowonjezereka kapena zowonjezereka (koma zikhoza kukhalapo kwa zigawo zina za audio monga olankhula, CD / DVD / owonetsera, etc.) zomwe zimagwiritsa ntchito maulendo osakhala a harmonic omwe adawonjezeredwa ku chizindikiro cholowera. Mofananamo ndi Total Harmonic Distortion , Kusokonezeka kwa Kugwiritsa Ntchito Mankhwala Osokoneza Bongo kumayesedwa ndipo kumaimira ngati peresenti ya chiwonetsero chonse chowonetsera. Ndipo monga momwe zimawonongedwera ndi Total Harmonic Distortion, nambala zocheperapo zimakhala bwino kuti ntchito ikhale yabwino.
Kusokoneza Magulu Amatha Kuchitika Ngati zizindikiro ziwiri kapena zingapo zimasakanizidwa kudzera mu chipangizo chopanda malire. Nyimbo zonse zimagwirizana, zimapanga amplitudes. Izi zimachititsa kupanga maulendo - omwe amatchedwa "sidebands" - osakhala nawo chizindikiro choyambirira. Popeza kuti maulendowa amatha kufalikira komanso amasiyana ndi maonekedwe oyambirira, amawoneka kuti si a harmoniki komanso osafunika chifukwa cha chikhalidwe chosagwirizana.
Kuti tifanizire, tizinena kuti chida chimodzi chimakhala ndi mawu ndipo chimapanga maulendo 440 Hz. Maulendo a Harmonic (zowonjezereka zowonjezera) kuti chida chichitike pa 880 Hz, 1220 Hz, 1760 Hz, ndi zina zotero. Ngati mphulupulu imapanga maulendo osakhala a harmonic a 300 Hz limodzi ndi mafupipafupi a 440 Hz, maulendo atatu a 740 Hz adzabwezeretsedwanso (440 Hz + 300 Hz), ndipo 740 Hz si harmonic ya 440 Hz. Motero, amatchedwa Intermodulation Distortion chifukwa ndi pakati pa maulendo a harmonic.
Chifukwa Chakusokoneza Maganizo Ndikofunika
Popeza kusokonezeka kwa ma Intermodulation Kusiyanitsa (osati harmoniki), ndiyeso yowonjezera. Ndipo pamene zilipo, ndizovuta kumvetsetsa ndi khutu kusiyana ndi kusokonezeka kwachiyanjano, chifukwa ma harmoniki amapezeka mu zizindikiro zomveka. Koma m'magulu a m'munsi ndi / kapena ndi nyimbo zosavuta, Kusiyanitsa kwa Intermodulation sikungakhale kotheka kwambiri. Kusiyanitsa tani kumatha kumveka bwino. Koma kamodzi kamodzi kowonjezera kumawonjezeka mpaka pomwe palibe kusiyana pakati pa zizindikiro, kusintha ndi kusagwirizana kwa maulendo a matope kapena kusokoneza chizindikiro choyambirira.
Zotsatirazi zikuphatikizidwanso ndi mitundu yovuta ya nyimbo (monga oimba nyimbo) pamene pali kugwirizana kwakukulu pakati pa maulendo onse. Ndipo zotsatira zake zikhoza kukhalanso phokoso la phokoso lomwe limapangitsa kuti awononge bwinobwino sonic komanso molondola. Pogwiritsa ntchito bwino, Kusokonezeka kwa Intermodulation kumabweretsa nyimbo zovuta, zophimba, kapena zopanda moyo. Choipa kwambiri, chirichonse chimamveka chokhwima ndi / kapena cholakwika kwambiri.
Komabe, monga kuwonongeke kwa Total Harmonic, Kusokonezeka kwa Kugwiritsa Ntchito Mankhwala Osokoneza Bongo kumakhala kochepa kotero kuti sikungatheke. Zamakono zamakono zamakono zalinganizidwa bwino kwambiri kuti kupanga Intermodulation Distortion kukhala yopanda phindu. Ingokumbukirani kuti makutu anu ndi woweruza wabwino wa khalidwe labwino, kotero musaweruze zigawo zikuluzikulu pokhapokha mwachindunji cha Intermodulation Distortion.
