Ewe, ii-simulators zikuvumela ukuba uvavanye iisekethe ngaphandle kwamalungu okwenene. Zibonisa indlela imiqondiso ehamba ngayo kunye nendlela amalungu asebenza ngayo kunye. Izixhobo ezifana ne-LTspice okanye iTinkercad zilungile kubaqalayo.
Ingcebiso ye-Emoji: 🖥️ Izilingisi zonga ixesha kwaye zinceda ukunqanda iimpazamo ezibiza kakhulu kwiisekethe zokwenyani.
Kuthekani ukuba andiwuqondi umzobo wesekethe?
Yiqhekeze ibe ngamacandelo amancinci. Gxininisa kwicandelo elinye, njengegalelo okanye imveliso. Khangela iisimboli ezingaziwayo okanye iinxalenye kwi-intanethi. Cela uncedo kwiiforam okanye kwizikhokelo.
Icebiso: Ziqhelise rhoqo ukuze ufumane ukuzithemba nokuphucula izakhono zakho.
Kutheni iilophu zempendulo zibalulekile kwiisekethe zeamplifier?
Iilophu zeengxelo zinceda ukulawula uzinzo kunye nokuzuza. Ingxelo engalunganga yehlisa ukugqwetheka kwaye iphucula ukuchaneka. Ingxelo encomekayo yongeza imiqondiso kodwa inokubangela ukungazinzi.
Phawula: Ukwazi iilophu zempendulo kukunceda uqonde iisekethe kwaye ulungise iingxaki ngcono.
