數(shù)字電路基礎(chǔ)知識(shí)畢業(yè)設(shè)計(jì)外文翻譯-預(yù)覽頁(yè)
【正文】 ard card level rises to the system level. The electric circuitdesign position only must use some standards the integrated circuitblock unit connection to bee. Also may use the programmableforeword logic array electric circuit regarding the non standardspecial electric circuit, through programming method realization freelogic function. Digital circuit application: Digital circuit and numeral electronic technology widespreadapplication to science and technology each domain and so ontelevision, radar, correspondence, electronic accounting machine,automatic control, astronautics. 數(shù)字電路定義： 用數(shù)字信號(hào)完成對(duì)數(shù)字量進(jìn)行算術(shù)運(yùn)算和邏輯運(yùn) 算的電路稱(chēng)為數(shù)字電路，或數(shù)字系統(tǒng)。特點(diǎn)是：輸出值只與當(dāng)時(shí)的輸入值有關(guān)，即輸出惟一地由當(dāng)時(shí)的輸入值決定。它類(lèi)似于含儲(chǔ)能元件的電感或電容的電路，如觸發(fā)器、鎖存器、計(jì)數(shù)器、移位寄存器、儲(chǔ)存器等電路都是時(shí)序電路的典型器件。電路的設(shè)計(jì)、維修、維護(hù)靈活方便，隨著集成電路技術(shù)的高速發(fā)展，數(shù)字邏輯電路的集成度越來(lái)越高，集成電路塊的功能隨著小規(guī)模集成電路（ SSI）、中規(guī)模集成電路（ MSI）、大規(guī)模集成電路（ LSI）、超大規(guī)模集成電路（ VLSI）的發(fā)展也從元件級(jí)、器件級(jí)、部件級(jí)、板卡級(jí)上升到系統(tǒng)級(jí)。
