Question

If the poles or zeros are repeated, then the function is said to be having __________ poles or ________ zeros.

(a) multiple, multiple

(b) simple, simple

(c) multiple, simple

(d) simple, multiple

This question was posed to me during an online interview.

This intriguing question comes from Poles and Zeros of Network Functions topic in section S-Domain Analysis of Network Theory

Answer 1

Right option is (a) multiple, multiple

The best explanation: If there are repeated poles or zeros, then function is said to be having multiple poles or multiple zeros and the network function is stable if the poles and zeros lie within the left half of the s-plane.
