Design a combinational circuit using multiplexer for a car chime based on the following system: A car chime or bell will sound if the output of the logic circuit (X) is set to a logic ‘1’. The chime is to be sounded for either of the following conditions: • if the headlights are left on when the engine is turned off and • if the engine is off and the key is in the ignition when the door is opened. Use the following input names and nomenclature in the design process: • ‘E’ – Engine. ‘1’ if the engine is ON and ‘0’ if the engine is OFF • ‘L’ – Lights. ‘1’ if the lights are ON and ‘0’ if the lights are OFF • ‘K’ – Key. ‘1’ if the key is in the ignition and ‘0’ if the key is not in the ignition • ‘D’ – Door. ‘1’ the door is open and ‘0’ if the door is closed • ‘X’ – Output to Chime. ‘1’ is chime is ON and ‘0’ if chime is OFF

(X) is set to a logic ‘1’. The chime is to be sounded for either of the following
conditions:
• if the headlights are left on when the engine is turned off and
• if the engine is off and the key is in the ignition when the door is opened.
Use the following input names and nomenclature in the design process:
• ‘E’ – Engine. ‘1’ if the engine is ON and ‘0’ if the engine is OFF
• ‘L’ – Lights. ‘1’ if the lights are ON and ‘0’ if the lights are OFF
• ‘K’ – Key. ‘1’ if the key is in the ignition and ‘0’ if the key is not in the ignition
• ‘D’ – Door. ‘1’ the door is open and ‘0’ if the door is closed
• ‘X’ – Output to Chime. ‘1’ is chime is ON and ‘0’ if chime is OFF
