## Homework Statement

Design [/B]:2-bit count-down counter; with two flip-flops and one input

## Homework Equations

When input = 0, the state of the flip-flops does not change.

When input = 1, the state is 11, 10, 01,11, and repeat.

## The Attempt at a Solution

Start with truth table, then characteristic table, and then excitation table, then Kmap?

How do I start deriving the truth table
