Morris Mano (5th edition) Exercise 3.18

Question

Draw a logic diagram using only two-input NOR gates to implement the following function:

$F(A,B,C,D)$ = $\left (A \oplus B \right )^{'} \left ( C \oplus D \right )$

Comments

using min number of NOR gate???

---

yes

Answer 1

 the circuit can be

Comments

$\left ( A^{'} + B \right )\left ( A + B^{'} \right )\left ( C + D \right )\left ( C{'} + D^{'} \right )$

is this correct?

---

yes you can write in this form also.But is this expression minimizing number of gates?

---

No yours is correct. (y)
