Orthogonal vectors are
A. Perpendicular to each other
B. Their dot product must be zero
C. One signal cannot interfere with the other
D. All of the mentioned
Answer:A
Orthogonal vectors are
A. Perpendicular to each other B. Their dot product must be zero C. One signal cannot interfere with the other D. All of the mentioned
Explanation: Orthogonal signals are perpendicular to each other, the inner or dot product between those two signals must equal zero, one vector has zero projection over the other because they do not share same signal space.
