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…

Logic circuit Design combinational logic circuit that takes 7 bit numbers and an input and output will be the reverse of this bits from right to left to the first one including one and remaining of the bits will be the same example input 0011000 output 0010111 Can you draw it’s logic circuit in detail not theory answer and if we can solve this question multiplexer

Please help me fill in the worksheet. And for the second part of the worksheet you have to make that circuit on TinkerCAD, with leds, etc.

Activity 5: An automated QA machine selects the product in an industry based on the perfection of color, weight, and length which are expressed by the variables C, W, and L, respectively. If a feature is perfect the machine takes input as '1', '0' otherwise. Based on the conditions, machine decides whether to reject (R) a product or not. Assume R = 1, if at least two of the features are not perfect. Otherwise, R = 0. Solve the following.

H.W: Reduce the combinational logic circuit in Figure below to a minimum form.

This is a logic gate simplification with certain laws to be followed. Please read the instructions on the given image, I will like your answer if you answered it properly and accurately. Thank you in advance

1. Consider the following two logic circuits. VDD A-6 B-d6 A-6 B-6 -6 -6 F VDD F t t A Circuit A Circuit B a. Do these two circuits implement the same logic function? If yes, what is that logic function? If no, give Boolean expressions for both circuits. b. Will these two circuits' output resistances always be equal to each other? c. Will these two circuits' rise and fall times always be equal to each other? Why or why not?
