If the factor of the form (s-a) in H(s) is mapped into 1-eaTz-1 in the z-domain, the that kind of transformation is called as:
A. Impulse invariance
B. Bilinear transformation
C. Approximation of derivatives
D. Matched Z-transform
Answer:A
If the factor of the form (s-a) in H(s) is mapped into 1-eaTz-1 in the z-domain, the that kind of transformation is called as:
A. Impulse invariance B. Bilinear transformation C. Approximation of derivatives D. Matched Z-transform
Explanation: If T is the sampling interval, then each factor of the form (s-a) in H(s) is mapped into the factor (1-eaTz-1) in the z-domain. This mapping is called the matched z-transform.
