Final answer:
To design a 3-bit ring counter, connect three D flip-flops in a circular manner and create a circuit diagram based on the truth table for each flip-flop. To design a twisted counter, also connect three D flip-flops in a circular manner, but this time connect the output of each flip-flop to the input of the previous flip-flop. Create a circuit diagram based on the truth table for each flip-flop.
Step-by-step explanation:
Designing a 3-Bit Ring Counter
To design a 3-bit ring counter, we need three flip-flops connected in a circular manner. Let's label the flip-flops as A, B, and C. We will use D flip-flops for this design.
