Question
1. Create a truth table for the following functional description. You are building a circuit which will output a 1 when the three of the four circuit inputs are equal. 2. Create the Karnaugh Map for this circuit. 3. Create a OrCad project with a schematic, page and simulation for this circuit. This means you will
have to build a stimulus file in order to test the circuit.
4. Create the truth table and k-map for a circuit which outputs a parity bit based on the values of the 4 inputs.
5. Add a new schematic folder to your project. Add a new page and using part 7486, build the circuit and simulate it. You may need to build a stimulus file with which to test your circuit.
NOTE: You may encounter an error that says something along the lines too many parts. If you see this error you need to consider how you can simplify the circuit.
