Which of the following is property of Z-transform?
Explanation: According to the linearity property of z-transform, if X(z) and Y(z) are the z-transforms of x(n) and y(n) respectively then, the z-transform of x(n)+y(n) is X(z)+Y(z).
What is the property of linearity of Z-transform?
Linearity. It states that when two or more individual discrete signals are multiplied by constants, their respective Z-transforms will also be multiplied by the same constants.
What are the two types of Z-transform?
The Z-transform may be of two types viz. unilateral (or one-sided) and bilateral (or two-sided).
