Question

Design a full 4-bit adder.

Include analysis, explanation and simulation (can be in multisim,
proteus or liviwire).

Answer #1

Sum outputs are provieded for each bit and a resultant carry (C4) is obtained from the fourth bit this adder featuer full internal look ahead across all four bits A4*n binary adder esaily bulit up by cascadeing without any additional logic gates

Logic simulation ,circuit simulation and re-simulation of circuit after circuit extraction is needed

Use contraction beginning with a 4-bit adder-subtractor with
carry in, to design a 4-bit circuit without carry out that
increments its input by 0010 for input S=0 and decrements its input
by 0010 for input S=1. Perform the design by designing the distinct
1-bit full adder cells needed and indicating the type of cell used
in each of the four bit positions.

Design a 1-bit Full adder using one 3-bit majority encoder and a
set of NAND gates

Design a Single cell 1 bit Carry propagate (or Ripple Carry
Adder) full adder.
a. Generate the truth table
b. Using K-map or Boolean algebra, determine the logical
expression for Carry out (C-out) and Sum (S) Outputs
C. Draw the circuit diagram of the outputs in step b

Q1)Design a 3-bit full adder by using a 8x3 Decoder.,
Q2)Design a digital circuit by using a 8x1 multiplexer
implementing the following Boolean equation.F(A, B, C, D) =∑(2, 3,
5, 7, 8, 9, 12, 13, 14, 15)

Design a 4-bit adder-subtractor circuit using the 4-bit binary
Full adders (74LS83) and any necessary additional logic gates. The
circuit has a mode input bit, M, that controls its operation.
Specifically, when M=0, the circuit becomes a 4-bit adder, and when
M=1, the circuit becomes a 4-bit subtractor that performs the
operation A plus the 2’s complement of B.Where A and B are two
4-bits binary numbers. That is,
* When M=0, we perform A+B, and we assume that
both...

Design a circuit that computes F = 4.5A (4.5 times A) using a
full adder. Input A is a 4-bit number (A3A2A1A0) and A is an even
number. A3 is the MSB.

by MULTISIM Design a 4 bit Counter that
displays even numbers when a switch on, and odd
when the switch off .
i want you to desgin that cirucit in MULTIsim by useing Jk flip
flop please make it easy to understand and memories =[
that mean if it was even= 0 its will count 0 , 2 , 4 ,6 , 8 , 10
, 14
if it is odd = 1 its will count 1 , 3 ,...

Design a 3 bit down counter that will start at 0, then 4, then
3, then 2, then 1, then 0, then 4... All unused states should go to
4. This should include state diagram, next state table, and
MultiSim schematic. Thanks!

Design a verilog code for four-bit subtractor. write the
simulation code and constraints file for nexys 4.

Adder
Start out by picking 2 positive six bit binary numbers that are
less than 3210, written in 2's complement notation. The
eventual goal is to add these two numbers.
1) Look at the LSB bit of the numbers, and using logic gates
(NANDs, NORs, etc.) design a circuit that correctly gives the right
output for any possible combination of bits in the LSB place.
2) Now look at the next column to the left (next to LSB). In
this...
