I have already made a diagram. However, it won't match the truth table that I have made, which I got from enter image description herethe logic converter in multisim. Could you please help me out with where did I go wrong? Is it on my diagram or in my truth table?

  • \$\begingroup\$ The truth table is definitely wrong. For example the 110 line. The circuit seem to be oversized too. Note that the expression is not sufficiently minimized. \$\endgroup\$

    \$\begingroup\$ I presume this is an academic exercise? Then you should have learned how to minimize boolean functions and build truth tables. \$\endgroup\$

  • \$\begingroup\$ @EugeneSh. It was difficult since my professor is not teaching at all. He just keeps on giving exercises and assessments. That's why I am here to ask guidance. \$\endgroup\$

  • \$\begingroup\$ From the truth table, your output X is the NAND of three inputs A, B, C. You have far too many gates to implement this simple function. \$\endgroup\$ Apr 22 at 15:19
