Ukuhlolisisa
Ukutjhugulula ukukhipha kwe-transistor engenako Iinqabo zokuphepha ezihlukanisiweko zidlulisa amatshwayo wokufaka avela ekutjhugululeni oxhumana nabo nofana ama-switch aseduze endaweni eyingozi ngokusebenzisa iinqabo zokuphepha ezihlukanisiweko ukuya endaweni ephephileko enemiphumela ye-transistor. Okufakwako kulawula umphumela we-transistor ongasebenziko oneemfanelo zokujamelana. Umphumela unemibandela emine echaziweko: ukujamelana kwe-alamu yesekhethi emfitjhani ≤ 240 Ω, i-1-signal 1.4KΩ ≤ inani lokujamelana ≤ 1.6KΩ, i-0-signal 13KΩ ≤ inani lokujamelana ≤ 14KΩ, kanye nokujamelana kwe-alamu ephukileko > 000 Ω. Ubunjalo bokukhipha buphendula ubujamo bomugqa emgqeni wesignali. Ama-dip switch wemojuli asetjenziselwa ukusetha okufakwako nokuphumako ngendlela efanako nofana ukulawula okubuyela emuva, kanye nokusetha umsebenzi wokutjengisa i-alamu yephutha lelayini. Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.
