Convolution of two sequences X1[n] and X2[n] are represented by:
A. X1(z)*X2(z)
B. X1(z)X2(z)
C. X1(z)+X2(z)
D. X1(z)/X2(z)
Answer:A
Convolution of two sequences X1[n] and X2[n] are represented by:
A. X1(z)*X2(z) B. X1(z)X2(z) C. X1(z)+X2(z) D. X1(z)/X2(z)
Explanation: Convolution of the two sequences is the combination of multiplication and addition of the two sequences at each instant and convolution in time domain is multiplication in the frequency domain.
