U2L1MajorityVote

A board of directors has asked you to design an electronics voting machine. The voting machine will allow the four board members to cast their ballots and will display the fass/fail status of each of their decisions.

The board of directors has four members; a president, a vice-president, a secretary, and a treasurer. Each member has a single yes/no vote. For a decision to pass, a majority of the board members must vote yes. In the event of a tie, the president’s vote is use to break the tie (i.e., If the president votes yes, the decision passes. If the president votes no, the decision fails.).

In this project you will use only AND, OR, & Inverter logic gates, frequently referred to as AOI logic, to design, simulate, and build a Majority Vote – Voting Machine that meets these design specifications.

Using the following variable names and assignment conditions, create a truth table shown for you Majority Vote - Voting Machine.

P: President 0 = No    1 = Yes
V: Vice President 0 = No    1 = Yes
S: Secretary 0 = No    1 = Yes
T: Treasurer 0 = No    1 = Yes
Decision   0 = Fail    1 = Pass

1.      Using the truth table, write the un-simplified logic expression for the output function Decision. Be sure that your answer is in the Sum-of-Products form.
2.      Design an AOI logic circuit that implements the un-simplified logic expression Decision. Limit your implementation to only 2-input AND gates (74LS08), 2-input OR gates (74LS32), and inverters (74LS04).
3.      Using the Multisim, enter and test your un-simplified Majority Vote – Voting Machine. Use switches for the inputs P, V, S, & T and a probe or LED circuit for the output Decision. Verify that the circuit is working as expected. Send me a copy of your final circuit.
4.      Using the theorems and laws of Boolean algebra, simplify the logic expression Decision. Be sure to put your answer in Sum-Of-Products (SOP) form.
5.      Design an AOI logic circuit that implements the simplified logic expression Decision. Limit your implementation to only 2-input AND gates (74LS08), 2-input OR gates (74LS32), and inverters (74LS04).
6.      Using the Multisim, enter and test your simplified Majority Vote – Voting Machine. Use switches for the inputs P, V, S, & T and a probe or LED circuit for the output Decision. Verify that the circuit is working as expected. Send me a copy of your final circuit.

7. Using a breadboard and IC chips, build and test the simplified Majority Vote – Voting Machine logic circuit that you designed and simulated. Verify that the circuit is working as expected and that the results match the results of the simulation.
