OFF
indicate the status of the door by the driver's seat, the ignition, and
the headlights, respectively. Design the logic circuit with these three
switches as inputs so that the alarm will be activated whenever either
of the following conditions exists:
• The headlights are on while the ignition is off.
• The door is open while the ignition is on.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0037f6d4-02ee-4e85-ba77-fd8ddb1cd9c1%2F51ea0652-dc9c-424e-bb26-2c36111a404c%2Frvb194q_processed.jpeg&w=3840&q=75)
