Homework # 11, due Monday 4/6

1. Show the complete state diagram for a 4-bit ring counter. Show all 16 states!

2. Show the complete state diagram for a 4-bit Johnson counter.
(Again, all 16 states)

3. Draw the complete state diagram for the self correcting ring
counter (circuit discussed in class).  Compare/contrast this
with state diagram for #1.

4. Draw the complete state diagram for a self correcting
Johnson counter.  Compare/contrast this with the state diagram from
# 2 above.

5. Hand in a Verilog implementation of the self-correcting
Johnson counter discussed in class.  Hand this in as a hard-
copy, with the rest of this assignment.
