QUESTION:
For each of the following algebraic expressions for the z-transform of a signal, determine the number of zeros in the finite z-plane and the number of zeros at infinity. 2(1- z-1) (c) (1- z- 1)(1 + z- 1)
ANSWER:Step 1 of 3
(a)
Calculating the zeros of the given z-transform by equating the numerator to zero,
For the first zero,
For the second zero,
Thus,
The system has one zero in the finite z-plane and one zero at infinity
