Spring 2003 ENGR 212 Homework 5

This homework is due ?? March, 4:30 PM.

Useful information

Copies of espress are also available on bulldog.unca.edu and the UNCA CSCI workstations.

Use the software tool espresso to minimize the circuits described in this homework. For each problem, you need to hand in a printout showing the input file and the espresso output. The printout should also have the output annotated to show the minimized function in algebraic form.

Problem 1

Minimize the following functions.

  1. f(a,b,c,d) = Σ(0,1,4,5,12,13)
  2. f(a,b,c,d,e) = Σ(0,4,18,19,22,23,25,29)
  3. f(v,w,x,y,z) = Σ(2,8,9,10,13,15,16,18,19,23) + d(3,11,17,22)
  4. f(x,y,z) = y z' + x' y z + x y z
  5. f(w,x,y,z) = x + x y z + x' y z + x' y + w x + w' x

Problem 2

Minimize the following triple of functions simultaneously, that is, with one espresso input file.
