Hello All,
After Block based FFT an overlap is done between blocks to remove
block artifacts. But my query is if i perform FFT on 512 block of
data, i get 512 freq samples output. If i continue this for 10 blocks i
will get 512 * 10 samples in freq samples then how can perform overlab
of the block? if i do i will be loosing data also and aliasing will be
thr.
Can any one explain how to perform overlap of block after FFT? and
also other advantages of it.
