- Perfect reconstruction
- Oversampled by 2
- Better channel isolation (
dB)
- Moderately robust to filter-bank modifications
This case is essentially the no-overlap rectangular-window case with the
window-length doubled and the window-transform squared, as derived in
Chapter 3. The squaring doubles the channel isolation in dB.
To move the folding frequency out to the first zero-crossing, 75%
overlap should be used (
oversampling in time).
