<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: Isibalo sangempela semigqa engu-525 sakhethwa njengomphumela wokulinganiselwa kobuchwepheshe besikhathi samanje obususelwa kumashubhu we-vacuum. Ezimisweni zokuqala ze-TV, i-oscillator elawulwa ngamandla kagesi yayisebenza ngokuphindwe kabili imvamisa yomugqa ovundlile, futhi le frequency yahlukaniswa phansi ngenani lemigqa esetshenzisiwe kulokhu 525 ukunikeza imvamisa yenkambu 60 Hz kulokhu. Le frequency yabe isiqhathaniswa ne-frequency ye-power-line engu-60 Hz futhi noma yikuphi ukungafani kwalungiswa ngokulungisa imvamisa ye-master oscillator. Ukuhlola okuhlanganisiwe, kwakudingeka inombolo engajwayelekile yemigqa ngefreyimu ngayinye ukuze kwenziwe ibanga lokubuyela emuva eliqondile elifanayo emikhakheni engajwayelekile neyi-even, okwakusho ukuthi imvamisa ye-master oscillator kwakudingeka ihlukaniswe phansi ngenombolo engajwayelekile. Umbuzo: Kwakunemigqa emingaki?  <response>: 525 izinkulungwane
