Problem #1
- Design a 4-bit adder.
- Each input bit has the same weight.
- Generate the boolean expressions for the bits that represent the sum of the 4 bits.
- Draw the schematics for the least significant output bit. You do not need to draw the schematics for all the bits, just the least significant one. Make sure you draw accurately the AND, OR, EXOR, or NOT gates. Put the part number inside or next to the gate, and add the pin numbers.
- Either scan, take a picture, or use a drawing/CAD package to create an electronic version of your diagram.
- Create a pdf that will contain all the answers to Problem #1. Call this pdf hw2.pdf, and submit it as follows:

Problem #2
- Complete the table below which shows the equivalent representations of unsigned integers in binary, hexadecimal, and decimal.
- Use as many bits are required.
- You are not allowed to use binary to decimal, or hexadecimal to decimal conversion tools. You can use calculators or computers to do multiplications and additions, though.
