##### ECET-105 Week 4 Lab: Logic Circuit Design, Simplification, Simulation & Verification

**Objectives:** The objective of this week’s lab was to design a digital logic circuit using a truth table and sum-of-product(SOP) formulation as well. We also figured out in this week’s lab how to access and use Multisim when using Boolean expressions and the truth table also. Finally, once we figured out how to how properly use Multisim, we started to build and test the logic circuit to verify that the system performs as expected.

**Results: **From the results from this week’s lab all of the objectives were accomplished.

**Conclusions: **I concluded from this week’s lab that a Boolean equation can always be converted……..

**Observations/Measurements:**

**Questions:**** **

- Using Multisim, simplify the following Boolean equations. (Hint: Enter the Boolean equation, use the Boolean to Truth Table button, then the Simplify Button.)
- Develop the truth table and Boolean SOP expression for the circuit shown below.
- Redraw the circuit for Question 2 using only NOT, AND, and OR gates.
