# Convert boolean expression to nand gate only. X = A'B'C+AB'C'+A'B'

I have already made a diagram. However, it won't match the truth table that I have made, which I got from the 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?

• 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. Apr 22 at 14:30
• @EugeneSh. what can i do about it? Apr 22 at 14:39
• I presume this is an academic exercise? Then you should have learned how to minimize boolean functions and build truth tables. Apr 22 at 14:44
• @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. Apr 22 at 14:51
• 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. Apr 22 at 15:19
