===== Assignment 6 =====

=== Due Monday, April 4, 2011 ===

  - Simplify f(A,B,C,D) = ∑(0,1,2,8,9,12,13), d(A,B,C,D) = ∑(10,11,14,15)
  - Design a 2 bit countdown circuit with T FFs. Counts: 3 2 1 0 3 2 1 0 . . . 
  - Design the circuit for the state diagram of Figure 1.  x and y are two inputs. Use S-R flip-flops.
  - pg 160 #39 - also create the state diagram (Moore).
  - pg 160 #40 - also create the state diagram. Note: x,y, and z are inputs, s is an output.
  - pg 160 #41 - also create the state diagram.
