The transfer function of a system is given as
Given = 2 
z + 1 
4 z - 1 z - 1 2 3
Consider the two statements
Statement (A) : System is causal and stable
Statement (B) : Inverse system is causal and stable
The correct option is
-
- (A) is true
- (B) is true
- Both are true
- Both are false
Correct Option: C
| Pole of system at: z = – | , | ||
| 2 | 3 |
| Pole of inverse system at: z = – | ||
| 2 |
For this system and inverse system all poles are inside | z| = 1. So, both system are both causal and stable.
