- Answer the following questions: 1. Design a 8 bit "shift left-shift right" register. 2. Design a 8 bit up counter. 3. Difference between sequential circuit vs combinational circuit. 4. Design a 8:1 multiplexer using 4:1 multiplexer and 2:1 multiplexer. 5. When designing register file, we used multiplexer to read from a specific register of that register file. However, to write in the register file, we didn't use demultiplexer. Why ? 6. In our designed register file, we can write one data at a time. But if we want to write two data at a time,what should we do ? 7.Logisim simulation: A. Design a 8 bit register file with 10 registers. B. Design an ALU with AND, OR, XOR, NOT, ADD and SUBTRUCT operations that can use the above register file. C. Create a single cycle data-path between register file and ALU. Save 1 digit of your NSU ID in each register of your register file before running instructions given below.E.g. for id: 1831565042, save 1 in first register, 8 in second, 3 in third and…H.W :- 1) A four logic-signal A,B,C,D are being used to represent a 4-bit binary number with A as the LSB and D as the MSB. The binary inputs are fed to a logic circuit that produces a logic 1 (HIGH) output only when the binary number is greater than 01102-610. Design this circuit. 2) repeat problem 1 for the output will be 0 (LOW) when the binary input is less than 01112-710- Saleem LateefSolve the problem and simplify the output function using Quine–Mc Cluskey Methods. The following requirements must be met in solving the problem. Requirement:a. Truth Tableb. Timing Diagramc. Quine – Mc Cluskey Method d. Logic Diagram A private company wants to decide on a certain issue. Each of the four officials has an equal share of voting right. At least two of them must approve the solution in order to implement it. Each of them has a switch which closes to vote YES and open to vote NO.
- Design a combinational circuit with the four inputs A,B.C, and D, and three outputs X, Y, and Z. When the binary input is odd number, the binary output is one lesser than the input. When the binary input is even number the binary output is one greate than the input. Implement the function using multiplexers with minimal input and select line.An 8-bit register contains the Hex value 2D. What is the register value after an arithmetic shift right? Starting from the initial number 2D, determine the register valuei) after logical shift rightii) after an arithmetic shift left, and state whether there is an overflow not, explain through the proper diagrams.Design a code converter that converts a decimal digit from BCD to excess-3 code, the input variables are organized as (A BC D) respectively with A is the MSB, the output variables are organized as (W XY Z) respectively with W is the MSB, put the invalid decimal numbers as don't care.

- 1. Assume that the registers are 8-bit wide. Consider the following code: MOV R1, #4A MOV R2, #40 ADD R3, R1, R2 a) What will be the 8-bit result in Register R3 (in hex)? b) What is the 8-bit result in Register R3 (as unsigned decimal)? c) What is the 8-bit result in Register R3 (as signed decimal)? d) What will be the value of the carry (C) bit?1. Gray code to Binary converter: Gray code is one of the codes used in digital systems. It has the advantage over binary numbers that only one bit in the code word changes when going from one number to the next. (See Table 1). Design a combinational circuit with 4 inputs and 4 outputs that converts a four- bit gray code number into an equivalent four-bit Binary number. Use Karnaugh map technique for simplification. Use LogicWorks for pre-lab demonstrations. Select the library "7400dev.clf* in the Parts Palette and then select the XOR chip 74-86. This would give you a set of 4 XOR's as shown in Fig. 1, just like the hardware chip 74-86. You could use as many as needed from these XOR gates in your design. Get back to ALL LIBRARIES and select switches for the inputs and Binary Probes as indicators of the outputs. Verify your design in the pre-Lab. During the Lab construct the circuit and verify its operations.answere fast please question from DIGITAL LOGIC DESIGN TOPIC : Designing Combinational Logic You are designing a water level circuit using 74ALS151 (8 to 1 Multiplexer IC)* When input is 0000 that means tank is empty.* When input is 1111 that means tank is full.* When input is below 5, that means water level is low.* So, make a circuit using 74ALS151 Multiplexer IC that shows a "low water" indicator light(by setting an output L to 1) when the water level drops below level 5.
