Q155

Let h(t) denote the impulse response of a causal system with transfer function 1 s + 1. Consider the following three statements: S1 : The system is stable. S2 : h ( t + 1 ) h ( t ) independent of t for t > 0. S3 : A non-causal system with the same transfer function is stable. For the above system,
