Which of the following is NOT one of the representations of discrete-time signals?

Which of the following statements concerning the LTI system is correct?

1. If the impulse response of an LTI system is periodic and non-zero, then the system is unstable.

2. the inverse of a causal LTI system is always causal.

3. the cascade connection of a non-causal LTI system with a causal one necessarily produces a non-causal system.
