Up-Down counter with enable using JK flip-flops: Design, construct and test a 2-bit counter that counts up or down.

Up-Down counter with enable using JK flip-flops: Design, construct and test a 2-bit counter that counts up or down. An enable input E determines whether the counter is on or off. If E = 0, the counter is disabled and remains in the present count even though clock pulses are applied to the flip-flops. If E= 1, the counter in enabled and a second input, x, determines the count direction. If x= 1, the circuit counts up with the sequence...
