What is the one sided z-transform of x(n)=δ(n+k)?
A. z-k
B. 0
C. zk
D. 1
Answer:A
What is the one sided z-transform of x(n)=δ(n+k)?
A. z-k B. 0 C. zk D. 1
Explanation: Since the signal x(n)= δ(n+k) is an anti causal signal i.e., it is defined for n<0 and x(n)=1 at z= -k. Since the one sided z-transform is defined only for causal signal, in this case X+(z)=0.
