1. Build a circuit in Logisim with the following characteristics:
2. Change your circuit from problem 1 so that it only uses decoders, OR gates, input pins, output pins, and wires.
3. Draw your circuit from problem 1 as a PLA.

m1 = 000 = A'B'C'
m3 = 011 = A'BC
m6 = 110 = ABC'
The Expression for W = A'B'C'+A'BC+ABC'
