Expert Solution
Step 1

Given:

In the above given question they want to know the logic diagram of a given Boolean expression.

 

In the question they have mentioned the sum of product terms of a digital circuit.

 

First of all for the given sum of minterms we need to write the truth table of the given Boolean expression.

 

From the truth table we can easily say that for which combination of inputs we will  get the logic 1 at the  output.
