The characteristic polynomial of system is (𝑠) = 2𝑠5 + 𝑠4 + 4𝑠3 + 2𝑠2 + 2𝑠 + 1 .   The system isSelect one:a. marginally stableb. stablec. unstabled. oscillatory

Which of the following is most stable?

What are the general criteria for achieving unconditional stability?a.K>1 and |Δ||Δ|<1b.K<1 and |Δ||Δ|<1c.K>1 and |Δ||Δ|>1d.K<1 and |Δ||Δ|>1

In the context of asynchronous sequential circuits, stability refers to:a.The unpredictability of circuit outputsb.The maintenance of a fixed circuit state over timec.The presence of consistent circuit oscillationsd.The ability to achieve high-speed operation

the feedback system with the characteristic equation 2s4 + 20ks3 + 3s2 + 5s + 7 = 0(a)stable for all value of k(b)stable fo rpositive value of k(c)stable for infinity>k>7.0(d)unstable for all values of k
