Homework Statement

(Problem 225) Design a synchronous circuit using negative edge-triggered D
flip- flops that provides an output signal Z which has one-fifth the frequency of the clock
signal. Draw a timing diagram to indicate the exact relationship between the clock
signal and the output signal Z. To ensure illegal state recovery, force all unused or
illegal states to go to 0. [Hint: There are many answers to this problem.]

my first step would be to thoroughly understand the concept of negative edge-triggered D flip-flops and their behavior in synchronous circuits. This would involve studying their truth tables, timing diagrams, and understanding how they differ from positive edge-triggered D flip-flops.

Next, I would carefully read and analyze the problem statement to fully understand the requirements and constraints. In this case, the goal is to design a synchronous circuit that uses negative edge-triggered D flip-flops to generate an output signal with one-fifth the frequency of the clock signal. Additionally, the circuit should ensure illegal state recovery by forcing all unused or illegal states to go to 0.

Based on this understanding, I would then start by creating a block diagram of the proposed circuit, outlining the inputs, outputs, and necessary components such as the negative edge-triggered D flip-flops. From there, I would begin to design the logic circuit that would generate the desired output signal Z.

This could involve using a combination of logic gates, counters, and other components to manipulate the input clock signal and generate an output signal with one-fifth the frequency. The exact design would depend on the specific requirements and constraints of the problem.

Once the logic circuit is designed, I would simulate it using a digital logic simulator to ensure that it functions as intended. If any issues or errors arise, I would troubleshoot and make necessary adjustments until the circuit is functioning correctly.

Finally, I would draw a timing diagram to illustrate the relationship between the clock signal and the output signal Z, ensuring that it meets the requirements of the problem. This diagram would show the timing of the clock signal and the output signal, including any delays caused by the negative edge-triggered D flip-flops.

In conclusion, designing a synchronous circuit using negative edge-triggered D flip-flops to generate an output signal with one-fifth the frequency of the clock signal would involve a thorough understanding of the concept, careful analysis of the problem statement, and a systematic approach to designing and simulating the circuit.
