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
