Part 1—Implement Part of a Seven-Segment Decoder Using AND-OR Logic Gates
Theory:
    For the following truth table, provide a Boolean expression that represents the truth table logic.
CBA    Y
000    0
001    0
010    0
011    1
100    0
101    1
110    0
111    1
    

Planning:
    Use Boolean algebra rules to simplify the answer to question #1.  Provide your simplification below:

Wiring Procedure:
    Which 7447 pins were disconnected prior to connecting the new circuit and rewired after the experiment ended?  What is the purpose of the new circuitry?

Test Procedure:
    Record the observed values from Lab 2 Table 2-1.  Indicate which segments are illuminated for each input.

Part 2—Process Control using Combinational Logic
Theory:
    Provide a truth table for the following Boolean expressions.
X=A ´B ´+A ´B
Y=A ´B+AB
AB    X    Y

    Draw a gate structure that represents the truth table.  Use Multisim to create the gate structure, use PrintScreen to capture the image and paste it into this report.
Test Procedure:
    Record the observed values from Lab 2 Table 2-2.  Indicate whether fluid is detected or not detected by each sensor.
Inputs    Fluid Detected- True or False
