A real valued signal x(n) is called as anti-symmetric if:
A. x(n)=x(-n)
B. x(n)=-x(-n)
C. x(n)=-x(n)
D. None of the mentioned
Answer:A
A real valued signal x(n) is called as anti-symmetric if:
A. x(n)=x(-n) B. x(n)=-x(-n) C. x(n)=-x(n) D. None of the mentioned
Explanation: According to the definition of anti-symmetric signal, the signal x(n) should be symmetric over origin. So, for the signal x(n) to be symmetric, it should satisfy the condition x(n)=-x(-n).
