Using JK flip flops, design a counter. The counter has one input x.
When x=0 the counter counts backwards as follows 7-6-5-4-3-2-1-0 .After the counter reaches 0 it goes
back to 7.
When x=1 the counter counts forwards as follows 0-1-2-3-4-5-6-7 After the counter reaches 7 it goes
back to 0.
a) Draw the state diagram.
b) Tabulate the state table.
c) Draw the logic diagram of the circuit.
