CSC 405 Lab 2 - Designing a Two Bit Comparator
with a Multiplexer In this laboratory exercise
you will implement a 4-variable Boolean
expression in a combinatorial circuit using an
8-to-1 multiplexer (74151A), and supporting logic
gates. Your circuit will compare two 2-bit
numbers A, B and indicate true if AgtB.
Your task is to design and implement a 2-bit
comparator that returns true (LED lights) if the
bit pattern presented at the input labeled A is
greater than that presented at B. 1. Complete the
following truth table for the AgtB operation.
4. Implement and test your circuit. To enable the
74151A you must connect the strobe line (pin 7)
to ground. The output Y is positive logic while
the output W is negative logic. Comments
