When multiple logic expressions are implemented, it is possible to reduce implementation cost by using the same signals in more than one expression. Repeat 4.4.1, but implement both Control signal 1 and Control signal 2, and try to “share” circuitry between expressions whenever possible.

Problem from 4.4.1

Implement the logic for the Control signal 1. Your circuit should directly implement the given expression (do not reorganize the expression to “optimize” it), using NOT gates and 2-input AND, OR, and XOR gates.


When implementing a logic expression in digital logic, one must use the available logic gates to implement an operator for which a gate is not available. Problems in this exercise refer to the following logic expressions:2 b. Control Signal 1 (((A AND B) XOR C) OR (A XOR C)) OR (A XOR B). (((A OR B) AND C) OR (CA OR C) OR (A OR

2 b. Control Signal 1 (((A AND B) XOR C) OR (A XOR C)) OR (A XOR B). (((A OR B) AND C) OR (CA OR C) OR (A OR B)) Control Signal 2 (A XOR B) OR (A XOR C) (A AND C) OR (B AND C)
