Topic: Signals and Systems
The output of a circular convolution performed on two signals $x_{1}(n)=\{\underline{2},1,2,1\}$ and $x_{2}(n)=\{\underline{1},2,3,4\}$ is
- A. (16, 14, 16, 14)
- B. (14, 16, 14, 16)
- C. (12, 14, 12, 14)
- D. (14, 12, 14, 12)
Answer: B. (14, 16, 14, 16)
Explanation: Using matrix multiplication after shifting, the circular convolution yields (14, 16, 14, 16).
