If the z transform of x(n) is X(z) =z(8z-7)/4z2-7z+3, then the final value theorem is :
A. 1
B. 2
C. ∞
D. 0
Answer:A
If the z transform of x(n) is X(z) =z(8z-7)/4z2-7z+3, then the final value theorem is :
A. 1 B. 2 C. ∞ D. 0
Explanation: Final value theorem is calculated for the transfer function by equating the value of z as 1 and this can be calculated only for stable systems.
