Q1:

The impulse response h[n] of a linear time invariant system is given by h[n] = ∪[n + 3 ] + ∪[n - 2] -2∪[n -7]. The above system is

A stable but non-casual

B stable and casual

C casual but unstable

D unstable and not casual

ANS:A - stable but non-casual

I think because its between -3 and 7 well I think that its bounded.
