Design a combinational circuit which compares two 4-bit unsigned numbers A and B. The circuit should have one output X such that X = 1 whenever A>B and X = 0 whenever A?B. You may use any MSI modules as well as any other gates.
X=(a1 & !b1)|(!(a1 xor b1) & (a2 & !b2))|(!(a1 xor b1) & (!(a2 xor b2)(a3 & !b3)) |(!(a1 xor b1) & (!(a2 xor b2)& (!(a3 xor b3)(a4 & !b4))
if highest bit of a is set but not the highest bit of b, =>
a>b
(a1 & !b1)
if highest bit is the same but second highest bit of a is set
but not second higest bit of b => a>b
(!(a1 xor b1) & (a2 & !b2))
if the two highest bit are equals but third highest of a is set
but not third highest of b => a>b
(!(a1 xor b1) & (!(a2 xor b2) (a3 & !b3))
if highest three bits are equals but lowest bit of a is set but
lowest bit of b isn't => a>b
(!(a1 xor b1) & (!(a2 xor b2) & (!(a3 xor b3)

Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether A is greater than B. The circuit has one output X, so that X = 0 if A ≤ B and X = 1 if A > B.
Design a combinational circuit that compares two 4-bit unsigned numbers A and B to see whether B is greater than 2A. The circuit has one output X, so that:X = 1 if 2A < B, andX = 0 if 2A >= B.Please de descriptive and detailed in drawing.The book we are using in class is this: http://www.cramster.com/logic-and-computer-design-fundamentals-4th-solutions-3631 and we are on chapter 4.
3. Design a combinational circuit that compares two 4 bit numbers (A and B) and has three outputs 'Z" and "M and 'O'.(20 points) a) The circuit output Z" is equal to 1 if the two numbers are equal and 0 otherwise (5 b) The circuit output M-1 ifA>B and 0 otherwise. A and B are considered unsigned e) The circuit output 'O'-1 ifA>B and 0 otherwise. A and B are considered signed points) numbers. (7.3 points) numbers. (7.5 points)
Combinational logic: a) Design a circuit to compare two numbers each is 1-bit: A, B. With 3 outputs X for A-B ,Y for A<B, Z for A B b) Use the previous output (or only one of them) as selection lines for a multiplexer to give the larger number to the output of the multiplexer.
Design a combinational circuit that adds 1 to 3-bit unsigned binary number and produces an unsigned binary result. Do the following: (1) determine the number of inputs/outputs, (2) write the truth table, (3) simplify the output functions by using maps and (4) draw the logic diagram by using AND OR and NOT gates. Show the truth table, the map, and the logic diagram. Do NOT use adders.
2. Build an 8-bit comparator that compares unsigned numbers A = a7 ao and B = b1" . bo and outputs 1 if A > B . First build a smaller unit (using K-map) with logic gates that compares two bit numbers X=x1x0 and Y =y,yo. Then, use sufficient number of these elements with required additional gates to build the final circuit.
Design a combinational circuit that accepts a 2-bit number and generates a 4-bit binary number output equal to the square of the input number. Use Decoder and any other external gates as necessary to implement your design. Draw the logic diagram and clearly label all input and output lines.
Digital design question. Combinational logic & building blocks. 9.1 Voting circuit. Using combinational building blocks such as adders, comparators, mul- tiplexers, decoders, encoders, and arbiters, as well as logic gates, design a circuit that accepts five three-bit one-hot numbers and outputs the three-bit one-hot number that occurred most often on the inputs. Ties can be broken in any manner. For example, if the inputs are 100, 100, 100, 010, and 001, the output will be 100
design and build a 4 bit binary multiplier that multiplies two 4 bit unsigned positive numbers to generate a 8 bit unsigned positive number. using full adders. do not use 4 bit multiplier chip. use truth table, karnaugh map and simplified output expression of the circuit.
Please design and implement a combinational circuit called 4-bit adder to add two 4-bit binary numbers, e.g. 1011 + 1110 = 1 1 0 0 1, the 5-bit result is 1 1 0 0 1 in which the leftmost bit is carry-out bit and sum result is 1 0 0 1, so that final sum is 1 1 0 0 1 which is 25 in decimal. (b) Design and Implement the four-bit adder circuit preferably using CEDAR logic simulator...
