What is the bipolar input and bipolar output truth table of ANDNOT function

Bipolar simply means replacing 0 by -1.

I forgot to clarify I know that. I am confused because table of mine and book are different. I just want a simple ANDNOT truth table. Can you provide that? or tell which one is correct?

Why does the book answer with 3 columns and you answer with 4 columns?

First, here is what you posted (we prefer not to have to click through to see images):

There are several questions here. First, I am not familiar with the name "ANDNOT"; it would be helpful to show the definition you were given. But the book's table (as you wrote it) is for "x₁ AND NOT x₂", that is, $x_1\wedge\neg x_2$, which is what I would expect it to mean. Your table is for "NOT(x₁ AND x₂)", that is, $\neg(x_1\wedge x_2)$. I would call the latter "NAND".

Second, your two handwritten tables are not for the bipolar form. Why?

Third, Table 13, which is in bipolar form, is also for "x₁ AND NOT x₂". It is true only when x₁ is true and x₂ is not.

Does any of this help?
