Answer:A
What is the kind of relationship between Ω and ω?
A. Many-to-one B. One-to-many C. One-to-one D. Many-to-many
Explanation: The analog frequencies Ω=±∞ are mapped to digital frequencies ω=±π. The frequency mapping is not aliased; that is, the relationship between Ω and ω is one-to-one. As a consequence of this, there are no major restrictions on the use of bilinear transformation.
