Binary Counters

Objective: Design, construct, and test a three-bit counter that countsup or down. Anenable input E determineswhether the counter is on or off.

· If E = 0, the counter is disabled and remainsat its present count eventhough clock pulses are appliedto the flip-flops.

· If E = 1, the counter is enabled and a second input, x, determines the direction of thecount.

· If x = 1, the circuit counts upward with the sequence 000, 001, 010, 011,100,101,110,111 and the count repeats.

· If x = 0, the circuit counts downward with the sequence 111,110,101,100,011,010,001,000 and the count repeats. (Do not use E to disable the Clock)

Note: Design the sequential circuit with E and x as inputs.

Submission:

Reports must include all schematics and cost of design.

Compare your results with other solutions.

Define why your design is better.

Welcome to AAC!

Post your best effort and we'll help guide you to a solution. Are you required to use any particular type of flip flop?

We won't do homework for you.

EDIT: Edit the title of your post to be more meaningful. Introductions should be in Off-Topic.

So, as dl324 said, post your best attempt to work your homework. That gives us the necessary starting point from which to help guide you to a solution.
