Ans 19) A system whose transfer function is improper rational( order of numerator > order of denominator) function is not BIBO(Vounded Input Bounded Output) stable ,regardless of location of it's poles and zeroes.
so correct answer is option D( Never).
Ans 20) zero input response is the response of the system in the absence of input excitation.
Correct answer is option B
D Question 19 1 pts When is a system whose transfer function is an improper rational...
When is a system whose transfer function is an improper rational function BIBO stable: Occasionally Sometimes Always Never Question 20 Response of the system in the absence of an input excitation is called: Step response Limited response Impulse response Zero input response
Question 17 1 pts Knowing the transfer function of a system is useful because: O It helps us calculate the weight of the system It does not really help us! It helps us find the response to any input function It helps us calculate the heat transferred by the system Question 18 1 pts A system is BIBO stable if all the poles of the transfer function (given that it is strictly proper rational) reside in: The origin The right...
