<prompt> Abaqambi bakhethe ukwenza imvamisa ye-chrominance subcarrier ibe yi-n 0.5 ephindwe kaningi emgqeni ukuze kuncishiswe ukuphazamiseka phakathi kwesiginali yokukhanya nesiginali ye-chrominance. Enye indlela lokhu okuvame ukushiwo ngayo ukuthi imvamisa ye-subcarrier yombala iyinombolo engaqondakali ephindwe kabili kwengxenye yemvamisa yomugqa. Bese bakhetha ukwenza imvamisa ye-subcarrier yomsindo ibe yi-integer ephindwe kaningi yomugqa ukuze kuncishiswe ukuphazamiseka okubonakalayo okuphambanisayo phakathi kwesiginali yomsindo nesiginali ye-chrominance. Izinga langempela elimnyama nomhlophe, elinemvamisa yomugqa ongu-15,750 Hz no-4.5 MHz, alihlangabezani nalezi zidingo, ngakho-ke abaklami kwadingeka ukuthi bakhuphule imvamisa ye-subcarrier yomsindo noma yehlise umugqa ophansi. Ukukhuphuka kwe-subcarrier yomsindo omhlophe kungavimbela imvamisa  <response>: 59.94 izinyanga
