(1) Givim ol stebol frikwensi signal
Ol 'frequency signal' we ol 'crystal oscillators' i save kamapim i save stap gut tru na ol i ken yusim olsem ol 'clock signal' bilong ol ilektronik divais, na dispela i mekim na ol divais i ken wok bihainim taim we ol i makim pinis taim ol i wok. Dispela em i bikpela samting long planti ol ilektronik samting we i nidim stretpela taim, olsem ol kompyuta, mobail fon, na ol samting bilong toktok.
(2) Mekim gut wok bilong ol divais
Long planti ilektronik divais, olsem ol 'microprocessor' na 'digital signal processor', 'stable frequency signal' we ol 'crystal oscillators' i save givim em i as bilong wok bilong ol divais. Sapos dispela signal i no stap, ol masin i no inap wok gut o i gat bikpela hevi long pefomens.
(3) Mekim wok bilong divais i kamap gutpela moa
Bikpela strong bilong ol 'crystal oscillators' i helpim wok bilong ol masin long kamap gutpela moa. Olsem, insait long ol masin bilong toktok, wanpela stebol frikwensi signal inap long mekim wok bilong salim data i go stret; insait long ol kompyuta, wanpela stebol klok signal inap long apim spit bilong prosesa, na ol narapela samting.
