Pinput A & AND 12 " Q1 OR OUT Pinput B Output D 13 NOT Pinput c For the given Function Block Diagram above regarding the input A, B, C and output D, which of the following Boolean expression could be used to represent the output D? Select one: O 1. None of them O 2. A.B+C 03. (A+B). C 0 4. A+B.C I I 2 Car Sensor: North 13 FCar Sensor: South OR 12345 14 PRESET COUNT Fcar Sensor: West I 5 15 Car Sensor: East To count the total of cars travelling through an intersection, the above FBD is proposed using four car sensors (detecting the car coming from each direction) and one upcounting counter. Which of the following statement is correct regarding this design? Select one: O 1. The wiring for the upcounting counter is not correct as the bottom left port should be connected, rather than the top left one. O 2. It can count the total of cars travelling through the intersection correctly. O 3. None of them is correct 4. The design is not correct as only one car will be counted when multiple car sensors are activated at the same time. 5. The logic design of the four car sensors is not correct as AND logic should be used, rather than OR
