Design a counter which counts in the sequence that has been assigned to you. Use D flip flops and NAND gates. Simulate your design using SimUaid.
Submit the state table, D flip-flop input equations, and transition graph determined in Part 6. The D flip-flop equations can be derived using Karnaugh maps or using LogicAid by entering a state table with zero input variables.
Sequence: 000,100,001,110,101,111,(repeat) 000,...
Also, please answer the following questions:
How can a D flip-flop be set to logic 0 without using the clock input?
How can it be set to logic 1 without using the clock input?
Explain the term Asynchronous Input.
Design a counter that counts in the sequence assigned to you. Use D flip-flops, NAND gates, and inverters. Draw your circuit explicitly showing all connections to gate and flip-flop inputs. Explicitly means that you should draw in all wires, don’t just label the inputs and outputs. Show switches connected to the Preset and Clear inputs of the flip-flops. Use one switch for all clears and a separate switch for each preset.
Explain in detail how you can set the flip-flops to the two missing states not in the prescribed counting sequence without using the clock input. Your explanation should describe each change you make to a switch position. After you have cleared or set a flip-flop, in what position (0 or 1) should you leave the switches?
