Using any design approach, plan and design the following problem: (show the Block Diagram, Truth Table, Simplification Approach Solution, Circuit Diagram) 2. Simple Security System A simple security system for two doors consists of a card reader and a keypad. Cand Reader To Door To Dor 2 To Alam Logic Circuit D E Keypad A person may open a particular door if he or she has a card containing the corresponding code and enters an authorized keypad code for that card. The outputs from the card reader are as follows: A B No card inserted Valid code for door 1 0 1 0 0 Valid code for door 2 1 1 Invalid card code 10 To unlock a door, a person must hold down the proper keys on the keypad and, then, insert the card in the reader. The authorized keypad codes for door 1 are 101 and 110, and the authorized keypad codes for door 2 are 101 and 011. If the card has an invalid code or if the wrong keypad code is entered, the alarm will ring when the card is inserted. If the correct keypad code is…
