This assignment reviews your background knowledge for the course. You will need to know material similar to this to succeed in the course.

1. (10%) Give a Boolean expression for the carry out resulting from the addition of two unsigned two-bit binary numbers in terms of all the bits of the numbers being added.

2.(10%) Show the representation of two numbers, -61 and 2 in 2's complement form, then add them. Use the least number of bits required for this.

3. (10%) Write the Boolean function for a full adder sum using the XOR function.

4.(10%) Implement the Boolean equation Z = A(BC + DEF) using only OR gates and inverters.
