Extracted text: Problem 1. Using Karnaugh maps find a minimal sum of products expression and a minimal product of sums expression for each of the following logic functions (a) F(W,X,Y,Z) = > (m,,m, m 4 m, , m1, m,3, m4) 7 (b) F(W,X,Y,Z) — П(М,,М, М , M,,М,, М, M ‚M 12, M 13 ,M 14) 9 : (c) F(W,X,Y,Z) = (m 4» m, , m,, m3 , m,5) + d(mo,m1,m7,m11,m12) (d) F(WXY) - ПОМ,М,,м,,М,,М ,) 3 Note: d(m;) means F(W,X,Y,Z) for the row of the truth table corresponding to the i'th minterm is "don't care".
