一個講解各種數位邏輯元件非常清楚的網頁

Play-hookey這個網站上面有許多有趣的資料。其中,在digital的部份他有一個網頁非常詳盡的解釋了各種基本邏輯元件的原理。同時還可以讓你直接在網頁上面操作這些邏輯元件,讓你能夠親身體驗這些元件實際的運作狀況。我覺得那些教邏輯設計的老師應該要把這個網頁列入教材中,讓學生能夠透過這個網頁更清楚的瞭解到邏輯元件的意義。這個網頁大約包含了如下的邏輯元件介紹:

  • Combinational Logic: Basic Gates, Derived Gates, XOR Function, Binary Addition, Negative Numbers and Binary Subtraction, Multiplexer, Decoder/Demultiplexer, Boolean Algebra
  • Sequential Logic: RS NAND Latch, RS NOR Latch, Clocked RS Latch, RS Flip-Flop, JK Flip-Flop, D Latch, D Flip-Flop, Flip-Flop Symbols, Converting Flip-Flop Inputs
  • Alternate Flip-Flop Circuits: D Flip-Flop Using NOR Latches, CMOS Flip-Flop Construction
  • Counters: Basic 4-Bit Counter, Synchronous Binary Counter, Synchronous Decimal Counter, Frequency Dividers, Counting in Reverse, The Johnson Counter
  • Registers: Shift Register (S to P), Shift Register (P to S)
  • The 555 Timer: 555 Internals and Basic Operation, 555 Application: Pulse Sequencer
