28.
The z- transform of a systerm is 
If the ROC is |z| < 0.2, then the impluse response of the system is
If the ROC is |z| < 0.2, then the impluse response of the system isAnswer: Option
Explanation:
ROC is |z| < 0.2, which shows x(n) must be non-causal, therefore sequence must be left handed.
But given 
is z-transform of right handed sequence.
But if H(z) become 
then ROC become |z| < 0.2 and inverse z-transform of 
is - (0.2)n ∪(- n - 1).
