Example: \( f = \sum m(0, 1, 2, 3, 7) = \bx_1 + x_1 x_2 x_3\)
 \(\bar{x_1}\)  \(x_1 \) 
 \(\bar{x_2}\)  \(x_2 \)  \(\bar{y}\) 
\(\bar{x_3}\) 
1  1  0  0 
\(x_3\) 
1  1+1  1  0 

Literals are
\( \bx_1, x_1, x_2, x_3\)

Implicants are \( \bx_1 \), \(\bx_1 x_2 x_3, \dots \), \( x_1 x_2 x_3\)

PI's are \( \bx_1 \) and \( x_2 x_3 \)

EPI's are \( \bx_1 \) and \( x_2 x_3 \)
