Simplifying the given Boolean expression \( \sim (\sim P \land Q) \land (\sim (\sim P \land \sim Q)) \lor (P \lor R) \), we observe that the expression simplifies to \( P \). Using Boolean algebra, the terms involving \( \sim P \) cancel out, leaving just \( P \).
Thus, the correct answer is option (4).
The supply voltage magnitude \( |V| \) of the circuit shown below is ____ .
A two-port network is defined by the relation
\(\text{I}_1 = 5V_1 + 3V_2 \)
\(\text{I}_2 = 2V_1 - 7V_2 \)
The value of \( Z_{12} \) is:
