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 detection of overflow in addition of two binary numbers in terms of specific bits of the numbers. The numbers are each 8 bits with one bit being the sign bit, in 2's complement form.

2.(10%) Show the representation of two numbers, -9 and 11 in 2's complement form. Use the least number of bits required for this.

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

4.(10%) Implement the Boolean equation Z = ABC + DEF using only AND gates and inverters.

5.(10%) What is the total area of a rectangle that is 0.090 nanometers x 1200 femtometers?

6.(10%) Two capacitors are in series. One is 55 fF and one is 54 fF. What is the total capacitance?

7.(10%) What is the relationship between current and voltage in a capacitor?

8.(10%) State Kirchoff's current law and voltage law.

9. (10%) The best way to store charge is a) resistor b) capacitor c) inductor?

10. (10%) A 14 ohm resistor is in parallel with a 7 ohm resistor. What is the total resistance?
