❶ 求數字電路的簡介,要有中英文對照的
數字電路定義:
用數字信號完成對數字量進行算術運算和邏輯運算的電路稱為數字電路,或數字系統。由於它具有邏輯運算和邏輯處理功能,所以又稱數字邏輯電路。
數字邏輯電路分類(按功能分):
1、 組合邏輯電路
簡稱組合電路,它由最基本的的邏輯門電路組合而成。特點是:輸出值只與當時的輸入值有關,即輸出惟一地由當時的輸入值決定。電路沒有記憶功能,輸出狀態隨著輸入狀態的變化而變化,類似於電阻性電路,如加法器、解碼器、編碼器、數據選擇器等都屬於此類。
2、 時序邏輯電路
簡稱時序電路,它是由最基本的邏輯門電路加上反饋邏輯迴路(輸出到輸入)或器件組合而成的電路,與組合電路最本質的區別在於時序電路具有記憶功能。時序電路的特點是:輸出不僅取決於當時的輸入值,而且還與電路過去的狀態有關。它類似於含儲能元件的電感或電容的電路,如觸發器、鎖存器、計數器、移位寄存器、儲存器等電路都是時序電路的典型器件。
數字電路的特點:
1、 同時具有算術運算和邏輯運算功能
數字電路是以二進制邏輯代數為數學基礎,使用二進制數字信號,既能進行算術運算又能方便地進行邏輯運算(與、或、非、判斷、比較、處理等),因此極其適合於運算、比較、存儲、傳輸、控制、決策等應用。
2、 實現簡單,系統可靠
以二進製作為基礎的數字邏輯電路,簡單可靠,准確性高。
3、 集成度高,功能實現容易
集成度高,體積小,功耗低是數字電路突出的優點之一。電路的設計、維修、維護靈活方便,隨著集成電路技術的高速發展,數字邏輯電路的集成度越來越高,集成電路塊的功能隨著小規模集成電路(SSI)、中規模集成電路(MSI)、大規模集成電路(LSI)、超大規模集成電路(VLSI)的發展也從元件級、器件級、部件級、板卡級上升到系統級。電路的設計組成只需採用一些標準的集成電路塊單元連接而成。對於非標準的特殊電路還可以使用可編程序邏輯陣列電路,通過編程的方法實現任意的邏輯功能。
數字電路的應用:
數字電路與數字電子技術廣泛的應用於電視、雷達、通信、電子計算機、自動控制、航天等科學技術各個領域。
Digital circuit definition:
Completes with the digital signal to the digital quantity carries onthe arithmetic operation and the logic operation electric circuit iscalled the digital circuit, or number system. Because it has the logicoperation and the logical processing function, therefore calls thenumeral logic circuit.
Numeral logic circuit classification (according to function minute):
1st, combinatory logic electric circuit
The abbreviation combination circuit, it becomes by the mostbasic logical gate electric circuit combination. The characteristicis: Output value only and then input value related, namely output onlyby then input value decision. The electric circuit has not rememberedthe function, the output condition changes along with the inputcondition change, is similar to the resistance electric circuit, likethe accumulator, the decoder, the encoder, the data selector and so onall belong to this kind.
2nd, succession logic circuit
The abbreviation sequence circuit, it is adds on the feedbacklogic return route by the most basic logical gate electric circuit (tooutput the electric circuit which input) or the component combinationbecomes, lies in the sequence circuit with the combination circuitessence difference to have the memory function. The sequence circuitcharacteristic is: The output not only was decided by then inputvalue, moreover also the and circuit past condition concerned. It issimilar to containing the stored energy part the inctance or theelectric capacity electric circuit, like electric circuit and so ontrigger, latch, counter, shift register, reservoir all is the sequencecircuit typical component.
Digital circuit characteristic:
1st, simultaneously has the arithmetic operation and the logicoperation function
The digital circuit is take the binary system logic algebra asmathematics foundation, the use binary numeral signal, both can carryon the arithmetic operation and to be able conveniently to carry onthe logic operation (with, or, non-, judgement, comparison, processingand so on), therefore extremely suits to application and so onoperation, comparison, memory, transmission, control, decision-making.
2nd, realization simple, the system is reliable
By binary system underlie numeral logic circuit, simplereliable, the accuracy is high.
3rd, integration rate high, the function realization is easy
Integration rate high, volume small, the power loss is low isone of digital circuit prominent merits. Electric circuit design,service, maintenance nimble convenient, along with the integratedcircuit technology high speed development, the numeral logic circuitintegration rate is more and more high, integrated circuit blockfunction along with small scale integration electric circuit (SSI),center scale integrated circuit (MSI), large scale integrated circuit(LSI), ultra large scale integrated circuit (VLSI) the developmentalso from the part level, the component level, the part level, theboard card level rises to the system level. The electric circuitdesign composition only must use some standards the integrated circuitblock unit connection to become. 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.

蔡氏電路(英語:Chua's circuit),一種簡單的非線性電子電路設計,它可以表現出標准回的混沌理論行為答。在1983年,由蔡少棠教授發表,當時他正在日本早稻田大學擔任訪問學者。這個電路的製作容易程度使它成為了一個無處不在的現實世界的混沌系統的例子,導致一些人聲明它是一個「混沌系統的典範」。
