Ukuthuthukisa Ubuqotho Bezimpawu Ngokulawulwa Kwe-PCB

--- # Isingeniso Emhlabeni wezobuchwepheshe banamuhla osheshayo, Ubuqotho besignali bubalulekile ekuqinisekiseni ukusebenza okuthembekile kwamadivayisi kagesi. Lapho amasiginali engaphathwa kahle, ukuphazamiseka nokuhlanekezelwa kungenzeka, okuholele ekungasebenzi kahle nokunciphisa ukusebenza kahle. Indlela eyodwa esebenzayo yokuthuthukisa ubuqotho besignali ngokusebenzisa izakhiwo ze-PCB ezilawulwayo. Kulesi sihloko, sizoqhuma
