Iifayili zekristale zomgca zizinto ezikhethekileyo ze-elektroniki ezidlala indima ebalulekileyo kunxibelelwano kunye neenkqubo zokuqhuba umqondiso. Ziyilelwe ukuvumela ngokukhetha ii-frequency ezithile ukuba zidlule ngelixa zihlasela abanye, ukwenza ukuba zibaluleke kakhulu kwizicelo apho ingqibelelo yomqondiso iphambili. Ngokusebenzisa iipropathi ze-resonant zeekristale ze-quartz, ezi hluzi zinokufezekisa phezulu
