PHY235 – INTRODUCTION TO DIGITAL LOGIC
LAB EXERCISE #4
The objective of this lab exercise is to implement a Boolean function using a multiplexer.
Multiplexers are useful for a variety of problems. To assist in understanding the functionality of a multiplexer, you will use one to implement a Boolean function.
It is possible to use a multiplexer to realize logic functions. For example, the function:
f(x, y, z) = xy + yz + xz
may be implemented using the SN74153 as shown below:

Using the procedure suggested in the textbook, construct the following function using a multiplexer:
f(x, y, z) = xyz + x'z'
Confirm proper operation of the circuit, and turn in a lab report.
