In Overlap save method of long sequence filtering, how many zeros are appended to the impulse response of the FIR filter?
A. L+M
B. L
C. L+1
D. L-1
Answer:A
In Overlap save method of long sequence filtering, how many zeros are appended to the impulse response of the FIR filter?
A. L+M B. L C. L+1 D. L-1
Explanation: The impulse of the FIR filter is increased in length by appending L-1 zeros and an N-point DFT of the sequence is computed once and stored.
