10. (24 pts.) You are to contribute to the digital hardware design associated with automobile buzzer. All input and output signals are described by the following table in the user specification. Signal DOOR Signal Description closed = HIGH, open - LOW in ignition = HIGH, not in ignition = LOW buckled = HIGH, not buckled = LOW occupied = HIGH, not occupied = LOW 'on = HIGH, off = LOW HIGH activates the buzzer This circuit should output a HIGH signal (to sound a buzzer) for each of the following conditions: KEYS SEAT BELT SEAT HEADLIGHTS Type Input Input Input Input Input Output BUZZER • If the driver's DOOR is open and the KEYS are in the ignition • If the SEATBELT is not buckled, the SEAT is occupied, and the KEYS are in the ignition • If the HEADLIGHTS are on and the KEYS are not in the ignition. a. (8 pts) Show the truth table that corresponds to the problem description. b. (8 pts) Use Karnaugh maps to derive minimal SOP expression for output. c. (6 pts) Sketch a logic schematic for function Buzzer, labelling all inputs/output clearly. You may assume both inverted and non-inverted inputs are available. 10. (24 pts.)
