z transform

3. type of quantization process.
4. If the present output is dependent upon the present and past value of input then the system is said to be ___________ system.
8. the values of z for which H(z) = α.
10. a process of converting discrete time continuous amplitude into discrete time discrete amplitude.
11. system have finite duration impulse response then the system is said to be ______system.
12. property of the z transform If z{x(n)}=X(z) & z{h(n)}=H(z) then, z{x(n)*h(n)}=X(z)H(z)
14. property of the z transform If z{x(n)}=X(z) then z{x(-n)}=X(z-1)
15. __________of DT system is defined as the ratio of Z transform of the system output to the input.

1. property of the z transform if z{x1(n)}=X1(z) and z{X2(n)}=x2(z) then, z{ax1(n)+bx2(n)}=aX1(z)+bX2(z) a&b are constants.
