<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Mutengo we59.94 unobva mukuverenga kunotevera. Vagadziri vakasarudza kuita kuti chrominance subcarrier frequency ive n 0.5 yakawanda yeiyo frequency frequency kuti ideredze kupindira pakati pechiratidzo che luminance uye chiratidzo che chrominance. Imwe nzira iyo iyi inowanzonzi ndeyekuti ruvara rwekutakura ruvara rwakawanda rwakawanda rwehafu yemutsara wenguva dzose. Ivo ipapo vakasarudza kuita odhiyo subcarrier kakawanda integer kakawanda mutsetse kakawanda kuderedza chinooneka intermodulation chipingaidzo pakati odhiyo chiratidzo uye chrominance chiratidzo. Nheyo yepakutanga yechitema nechena, nechiverengero chayo che15,750 Hz uye 4.5 MHz subcarrier audio, haisangane nezvinodiwa izvi, saka vagadziri vaifanira kukwirisa frequency ye subcarrier audio kana kudzikisa frequency yemutsetse. Kukwidziridza ruzha rwekutakura ruzha kwaizodzivisa zviripo zvitsvuku uye zvichena zvinogamuchira kubva pakugadzirisa zvakanaka mucherechedzo wezwi. Kuderedza mutsetse frequency ari comparatively ngozi, nokuti chinjikira uye hunyambiri synchronization mashoko ari NTSC chiratidzo anobvumira mugamuchiri kuti kushivirira yakawanda uwandu musiyano mutsetse frequency. Naizvozvo mainjiniya akasarudza kuti rwonzi rwuchinjwe kuti ruve noruvara rwakajairika. Muchiedza chemavara matema nemachena, chiyero chemavara e-audio subcarrier frequency kusvika kune line frequency ndeye 4.5 MHz 15,750 Hz 285.71. Muchimiro chemavara, izvi zvinokomberedzwa kunhamba yakazara 286, zvinoreva kuti chiyero chemuvara chemuvara ndeye 4.5 MHz 286 15,734 Hz. Kuchengeta nhamba yakafanana yemitsetse yokunzvera pamunda uye furemu, mwero wakaderera wemutsetse unofanira kupa mwero wakaderera wemunda. Kuparadzanisa mitsetse 4500000286 pasekondi nemitsetse 262.5 pamunda kunopa anenge minda 59.94 pasekondi. Mubvunzo: Kugoverwa kunobereka inenge minda yakawanda zvakadini pasekondi?  <response>: 59,94 Makore makumi mashanu nemapfumbamwe
