Boolean Expression
1. The problem is to draw the logic circuit for the Boolean expression:
$$ (xyz) + (x+y+z)' + (x'zy') $$
2. Let's break down the expression into parts.
- The term $xyz$ means AND of $x$, $y$, and $z$.
- The term $(x+y+z)'$ means the complement (NOT) of the OR of $x$, $y$, and $z$.
- The term $x'zy'$ means AND of NOT $x$, $z$, and NOT $y$.
3. Steps to build the circuit:
- Create inputs $x$, $y$, $z$.
- For $xyz$, use an AND gate with inputs $x$, $y$, $z$.
- For $(x+y+z)'$, first use an OR gate with inputs $x$, $y$, $z$, then feed its output into a NOT gate.
- For $x'zy'$, use NOT gates for $x$ and $y$ to get $x'$ and $y'$, then use an AND gate with inputs $x'$, $z$, $y'$.
- Finally, use an OR gate to combine the outputs from the three terms: $xyz$, $(x+y+z)'$, and $x'zy'$.
4. The final output is from this OR gate.
This logic circuit implements the given Boolean expression correctly.
