Is there a systematic way in which l can determine the behavior of this sequential circuit ?

I think my signals for Q0, and Q1 correspond with your answer, just not Q2.Jegues, I 'm afraid you didn't quite get it.
You see, there is a small time frame before the output of the first FF is updated with the input. At that time frame, the HIGH signal hasn't yet reached the input of the second FF but the clock positive front has expired. Consequently the second FF won't be updated simulatneously with the first.
Check the image for a general picture. Don't bother about the amplitudes, I have offset them anyway. From up to down we have the clock and the 3 FFs.
Sure enough, it took 8 cycles to make a full period.
Yes but on my figure I did not start with a HIGH clock pulse, I started with a LOW clock pulse.Nor Q1 or Q2 correspond to my answer. I should have pointed it out more, but Q0 starts rising at time 0, the same time the first clock pulse comes.
Both Q1 and Q2 stay at LOW at time 0+.
Which varsity are you at ?I have the exact same question on my assignment. We must both share the same terrible professor.
I've given an attempt at drawing the timing diagrams, they are attached to this post.
I'm not 100% if this is right, or if it has enough clock pulses to completely describe the behaviour of our sequential circuit, but hopefully (if it's right) it will give you a better idea of what to do.
I suggest having the T flip flop excitation table handy while drawing the timing diagram if you aren't comfrotable with them yet.
As far as the delay between the flip flops would this be correct:A duration of \(T_{\tiny{LOW}}\) to be exact.
And, yes, Q0, Q1 and Q2 will wait at LOW until the first clock pulse starts the sequence.
