1.	Let h(t) denote the impulse response of causal system with transfer function \(H\left( s \right) = \frac{1}{{s + 1}}\) Consider the following three statements S1: The system is stable S2: \(\frac{{h\left( {t + 1} \right)}}{{h\left( t \right)}}\) is independent of time S3: A non – causal system with same transfer function is stable for the above system
A.	Only S1 is true
B.	Only S3 is true
C.	Only S1 and S2 are true
D.	Only S1 and S3 are true
Answer» D. Only S1 and S3 are true
