If X+(z) is the one sided z-transform of x(n), then what is the one sided z-transform of x(n-k)?
Explanation: From the definition of one sided z-transform we have,

If x(n)=an, then what is one sided z-transform of x(n-2)?
Question 9
Marks : +2 | -2
Pass Ratio : 100%
If x(n)=an, then what is one sided z-transform of x(n+2)?
Explanation: We will apply the time advance theorem with the value of k=2.We obtain,
Question 10
Marks : +2 | -2
Pass Ratio : 100%
What is the one sided z-transform X+(z) of the signal x(n)={1,2,5,7,0,1}?
Explanation: Since the one sided z-transform is valid only for n>=0, the z-transform of the given signal will be X+(z)= 5+7z-1+z-3.
