  1. OBJECTIVE
  2. The objective of this lab exercise is to implement a Boolean function using a multiplexer.

  3. EQUIPMENT
  1. PAD-234
  2. SN74153
  1. DISCUSSION
  2. 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.

  3. EXERCISE

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.
