Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Poles of a transfer function are the values of s that make the denominator zero.
\( H(s) = \frac{1}{(s + 3)^2} \)
Set the denominator equal to zero to find the poles.
Calculation:
\( (s + 3)^2 = 0 \Rightarrow s + 3 = 0 \Rightarrow s = -3 \)
Since the power is 2, it means the pole is of multiplicity 2 (repeated pole).
Hence the correct option is 3
