What is the associative property of discrete time convolution?

A. [x<sub>1</sub>(n) * x<sub>2</sub>(n)]*h(n) = x<sub>1</sub>(n)* [x<sub>2</sub>(n)*h(n)]
B. [x<sub>1</sub>(n) * x<sub>2</sub>(n)]+h(n) = x<sub>1</sub>(n) + [x<sub>2</sub>(n)*h(n)]
C. [x<sub>1</sub>(n) + x<sub>2</sub>(n)]*h(n) = x<sub>1</sub>(n)* [x<sub>2</sub>(n)+h(n)]
D. [x<sub>1</sub>(n) * x<sub>2</sub>(n)]h(n) = x<sub>1</sub>(n) [x<sub>2</sub>(n)*h(n)]
Answer» B. [x<sub>1</sub>(n) * x<sub>2</sub>(n)]+h(n) = x<sub>1</sub>(n) + [x<sub>2</sub>(n)*h(n)]
