Design a mod-6 UP/DOWN counter:
A) Using JK flip-flops and the state equation method. (Show the state diagram, state table, state equations, flip-flop input equations, and the logic diagram.)
B) Using D flip-flops and the state equation method. (Show the state diagram, state table, state equations, flip-flop input equations, and the logic diagram.)
C) Using D flip-flops and the "one-hot" method. (Show the state diagram, the ASM chart, and the logic diagram.)
