  2. 實驗元件 • TTL 7486 (2 Input XOR) • TTL 7408 (2 Input AND) • TTL 7432 • DIP SW 8 Pin • 1KΩ *2 • 220Ω *2 • LED

  3. 實驗元件簡介 • TTL 7408

  4. 實驗元件簡介 • TTL 7486

  5. 實驗元件簡介 • DIP SW 8 Pin A B C D

  6. Truth table

  7. 半加器 • 不具進位輸入的1-Bit加法器 • 全加器 • 具進位輸入的1-Bit加法器 • 2-Bit加法器 • 整合一個全加器及一個半加器而成 • n-Bit加法器 • 整合n - 1個全加器及一個半加器而成 • 2補數 • 1’s complement • 2’s complement • A-B=A+(2’complement of B) • 利用二補數,使加法器可執行減法動作

  8. 實驗步驟

  9. 完成滿足下列真值表的1-Bit半加器

  10. 完成滿足下列真值表的1-Bit全加器

  11. 實驗問題 • 推導如何應用全加器及半加器來建立n-Bit的加法器 • 加法器為一切算數邏輯的基礎,試簡單說明加法器如何運用在乘法器及除法器上?
