What are methods of real-world purpose that using logic gates can implement? Explain deeper if using our listed impacts, explaining why this impact is helpful.
Example 1: Security Alarm System (Using Logic Gates)
- A house alarm uses an OR gate.
- If door opens OR window breaks an alarm will sounds
Why logic gates help:
- The OR gate makes it so either problem (door or window) triggers protection.
- It keeps homes safe by detecting any break-in fast.
Example 2: Traffic Light Controller (Using Logic Gates)
How it works:
- A city traffic light uses AND gates and NOT gates.
- If car at intersection AND timer says green → Light turns green.
-
If no cars (NOT car detected) → Keep light red or switch faster.
- Traffic flows smoothly without wasting time.
- Prevents crashes and saves gas by reducing long wait times at empty intersections.

A digital circuit receives three binary inputs: X, Y, and Z. The circuit outputs 1 if and only if X AND Y are both 1, OR Z is 1.
Which of the following expressions represents the circuit’s behavior?
A. (X AND Y) OR Z B. X AND (Y OR Z) C. (X OR Y) AND Z D. NOT(X AND Y) OR Z
A is the correct answer
