First you must create a logic circuit using only basic gates such as AND, OR, NOR, NAND, NOT, etc. to implement an ADDER capable of adding two 4 bit binary numbers. Second you must create a logic circuit using only basic gates such as AND, OR, NOR, NAND, NOT, etc. to implement a Subtractor that is capable of subtracting the second number from the first, by converting the second number into its 2's complement form and then adding the resulting...

[Paperl (10 pts.) Design a circuit that takes in four 4-bit unsigned numbers, A (A3..Ao), B (B3..Bo), C (C3-C), and D (D3..Do) and produces the 6-bit unsigned sum of those numbers. You should use three 4-bit adder blocks (74LS283's), and a minimal number of full adders or half adder build blocks. You should organize your adder circuits to perform as many additions in parallel (at the same time) as possible. Getting started: Write out the columns of addition and see...

You are to design a circuit that calculates the Hamming distance between two 5-bit numbers. It takes two 5-bit binary numbers A4 A3 A2 A1 A0 and B4 B3B 2B1 B0 as inputs and returns the number of bits that are different between the two numbers as the 3-bit binary output O2 O1 O0. For example: *If the two input numbers were 10111 and 00001 then the output would be 011 as there are 3 bits different between them. *If...
