The anti-symmetric condition with M even is not used in the design of which of the following linear-phase FIR filter?
A. Low pass
B. High pass
C. Band pass
D. Bans stop
Answer:A
The anti-symmetric condition with M even is not used in the design of which of the following linear-phase FIR filter?
A. Low pass B. High pass C. Band pass D. Bans stop
Explanation: When h(n)=-h(M-1-n) and M is even, we know that H(0)=0. Thus it is not used in the design of a low pass linear phase FIR filter.
