1. Create a 2-input AND function using only NAND gates a) Draw the block diagram, showing the gate connections b) Generate truth tables for each stage of the function 2. Create a 2 -input OR function using only NAND gates a) Draw the block diagram, showing the gate connections b) Generate truth tables for each stage of the function 3. The NOR gate is defined as NOT OR (or the opposite of OR). Create an inverter function using only NOR gates a) Draw the block diagram, showing the gate connections b) Generate truth tables for each stage of the function 4. Create a 2 -input AND function using only NOR gates a) Draw the block diagram, showing the gate connections b) Generate truth tables for each stage of the function 5. Consider the 2 digital logic circuit shown below. Treat the small circle as the inverter (NOT) function. a) Create the truth table and write the logical expression for \( Z \) - e.g., the expression for NAND is \( \mathrm{Z}=-(\mathrm{A} \cdot \mathrm{B}) \) b) Identify the name of this logical function (discussed in class)
