[問題]求解一題邏輯設計

[lwnkawasaki (lwnkawasaki)]

Q:Use the NAND gates and NOT gates as few as possible to design a circuit that converts a 4-bit binary number to its corresponding two-digit BCD number .For example, if the input is D3D2D1D0=1100,then the out will be H3H2H1H0L3L2L1L0=0001 0010(12)

(a)write out the corresponding truth table.

(b)Derive the logic function for L2 in the form of product-of sum(POS)

(c)Design the circuit for L2 with NAND gates or NOT gates as few as possible.

In case it is needed,Karnaugh mapes may be used to simplify the logical function.

可以幫我解釋題目,並替我解出(a)(b)(c)3小題的答案嗎..謝謝^^

推 cool2711992:你先把真直表畫出來 就2進制轉bcd
→ cool2711992:然後對L2化簡  用POS方式
→ cool2711992:出來就可畫電路圖了
→ lwnkawasaki:可以請教要怎麼寫出這題真值表嗎??因為沒上過邏輯設計
→ lwnkawasaki:是自己研讀的..所以不知能否教我畫這題的真值表
→ lwnkawasaki:畫出來後我就會(B)(C)小題了..謝謝!!
推 cool2711992:你翻去看BCD那邊就知道了 懂原理就會了
