What is the value of H M 1/2 if the unit sample response is anti symmetric?

What is the value of h(M-1/2) if the unit sample response is anti-symmetric? Explanation: When h(n)=-h(M-1-n), the unit sample response is anti-symmetric. For M odd, the center point of the anti-symmetric is n=M-1/2. Consequently, h(M-1/2)=0.
