Discrete Math Problems: Boolean Algebra
1. Let x, y be elements in the Boolean algebra B. Prove that
x = y if and only if xy + xy = 0.
2. a. How many rows are needed to construct the (function)
table for a Boolean function of n variables?
b. How many different Boolean functions of n variables are
there?
3. Let g: B4 ?B be defined by g(w, x, y, z) = (wz + xyz)(x +
x yz).
a. Find the d.n.f. and c.n.f. for g.
b. Write g as a sum of minterms an d as a product of
maxterms (utilizing binary labels).
4. Obtain a minimal-product-of-sums representation for f (w,
x, y, z) IIM(0, 1, 2, 4, 5, 10, 12, 13, 14).
5. Let f, g: B5 ?B be Boolean functions, where f =?m(1, 2,
4, 7, x) and g = ?m(0, 1, 2, 3, y, z, 16, 25). If f ? g, what are x, y, z?
