2. Design and Construct a parallel counter that has the following sequence. If the input (UP)/(DOWN)' = 1, it will count up, 000-010-100-110 and then recycle to 000 If the input (UP)/(DOWN)' = 0, it will count down, 110-100-010-000 and then recycle to 110. Undesired states are don't care states. (1) Use D flip-flops for the design.
