The logical expressions are
- (X NOR Y ) OR Z ⇒

- (A NAND B) AND NOT C ⇒

<h3>How to determine the
logical expressions?</h3>
<u>Logical expression 1</u>
X and Y are linked by the NOR gate.
So, we have:
X NOR Y
The X NOR Y is linked to Z by the OR gate.
So, we have:
(X NOR Y) OR Z
Hence, the logical expression is (X NOR Y ) OR Z ⇒ 
<u>Logical expression 2</u>
A and B are linked by the NAND gate.
So, we have:
A NAND B
The A NAND B is linked to C by the AND gate.
So, we have:
(A NAND B) AND C
Hence, the logical expression is (A NAND B) AND NOT C ⇒
