Example so far: Here is the truth table for the expression from slide 44:
| $x$ | $y$ | $z$ | $E$ |
|---|---|---|---|
| $0$ | $0$ | $0$ | $0$ |
| $0$ | $0$ | $1$ | $0$ |
| $0$ | $1$ | $0$ | $1$ |
| $0$ | $1$ | $1$ | $1$ |
| $1$ | $0$ | $0$ | $0$ |
| $1$ | $0$ | $1$ | $0$ |
| $1$ | $1$ | $0$ | $0$ |
| $1$ | $1$ | $1$ | $1$ |
The table contains 4 columns (and describes an expression that uses 3 types of variables, $x$, $y$, and $z$,) so we'll create a 3-variable Kmap.
