1.Design a block diagram for an alarm that triggers if a door is open AND either a window OR motion is detected.
2.Convert this block diagram to a logic diagram: [Switch A] → [OR Gate] ← [Switch B] → [AND Gate] ← [Power] → [Light].
3.How can AND and NOT gates control a traffic light that turns green only if a sensor is off AND a timer is on?
4.Design a system where a fan runs if it’s hot OR humid, but NOT both. Draw the block diagram.
5.Create a logic diagram for a system where a bell rings if either a teacher OR student is present, but NOT if both are.
