Challenge Problems
Push your limits with challenges.
Question 1
A plant has three parameters: temperature, pressure, and flow rate. Design an OR gate system that triggers an alarm when any one of these parameters exceeds safe limits. Describe your circuit's components and function.
💡 Hint: Think of how you would wire the sensors and their outputs to activate the alarm.
Question 2
How would you adjust a system that uses OR gates if it needs to ensure all conditions for safety are met before alerting? Transition it to using AND gates.
💡 Hint: Consider how the logic needs to change from any one signal to all signals.
