Question

The sampling interval in the matched z-transform must be properly selected to yield the pole and zero locations at the equivalent position in the z-plane.

(a) True

(b) False

I have been asked this question in an international level competition.

This is a very interesting question from Matched Z Transformation topic in chapter Digital Filters Design of Digital Signal Processing

Answer 1

Right option is (a) True

Explanation: To preserve the frequency response characteristic of the analog filter, the sampling interval in the matched z-transformation must be properly selected to yield the pole and zero locations at the equivalent position in the z-plane.
