D Question 19 1 pts When is a system whose transfer function is an improper rational function BIBO stable: Sometimes Occasionally Always Never Question 20 1 pts Response of the system in the absence of an input excitation is called: Impulse response Zero input response Limited response Step response

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.
