Figure 1 shows a schematic diagram for an automobile alarm circuit used to detect certain undesirable conditions. The three switches are used to indicate the status of the door (Input A) by the drivers seat, the ignition (Input B), and the headlights (Input C), respectively. Design the logic circuit with these three switches as inputs so that the alarm is activated whenever either of the following conditions occur. Show all the design steps.

The headlights are on while the ignition is off

The door is open while the ignition is on

(Assignment 2) - Session - ALL (5 Marks) 2 (45 Marks) a) Figure 1 shows a schematic diagram for an automobile alarm circuit used to detect certain undesirable conditions. The three switches are used to indicate the status of the door (Input A) by the driver's seat, the ignition (Input B), and the headlights (Input C), respectively. Design the logic circuit with these three switches as inputs so that the alarm is activated whenever either of the following conditions occur. Show all the design steps. i) The headlights are on while the ignition is off ii) The door is open while the ignition is on (12 Marks) +5V +5V Door Open Closed - LED +5V ON Ignition Alarm Logic circuit OFF +5 V ON Lights OFF
