s³ + s² + 2s + 24
Then the network is:
Options
A. stable
B. oscillatory
C. unstable
D. depends on numerator polynomial

Correct Answer

unstable

Explanation

Routh array

Denominator polynomial of a transfer function of certain network is: s3 + s2 + 2s + 24 Then the netw

There is negative number present in first column. Thus network is unstable.
