If Z{x1(n)}=X1(z) and Z{x2(n)}=X2(z) then what is the z-transform of correlation between the two signals?
A. X1(z).X2(z-1)
B. X1(z).X2(z-1)
C. X1(z).X2(z)
D. X1(z).X2(-z)
Answer:A
If Z{x1(n)}=X1(z) and Z{x2(n)}=X2(z) then what is the z-transform of correlation between the two signals?
A. X1(z).X2(z-1) B. X1(z).X2(z-1) C. X1(z).X2(z) D. X1(z).X2(-z)
Explanation: We know that rx1x2(l)=x1(l)*x2(-l)
