The z-transform of a signal x(n) whose definition is given by is known as:
A. Unilateral z-transform
B. Bilateral z-transform
C. Rational z-transform
D. None of the mentioned
Answer:A
The z-transform of a signal x(n) whose definition is given by is known as:
A. Unilateral z-transform B. Bilateral z-transform C. Rational z-transform D. None of the mentioned
Explanation: The z-transform of the x(n) whose definition exists in the range n=-∞ to +∞ is known as bilateral or two sided z-transform. But in the given question the value of n=0 to +∞. So, such a z-transform is known as Unilateral or one sided z-transform.
