Which of the following is true in case of Overlap add method?
A. M zeros are appended at last of each data block
B. M zeros are appended at first of each data block
C. M-1 zeros are appended at last of each data block
D. M-1 zeros are appended at first of each data block
Answer:A
Which of the following is true in case of Overlap add method?
A. M zeros are appended at last of each data block B. M zeros are appended at first of each data block C. M-1 zeros are appended at last of each data block D. M-1 zeros are appended at first of each data block
Explanation: In Overlap add method, to each data block we append M-1 zeros at last and compute N point DFT, so that the length of the input sequence is L+M-1=N.
