Octave Filter Bank Using Chebyshev Window

$\epsfig{file=eps/impulse-cheb127h-rect129x-N256-aliased-partition-interp.eps,width=0.9\textwidth }$

Same as before but with critical downsampling of each channel signal
All this stopband error cancels out in the filter-bank sum because the input signal is an impulse (reconstruction remains exact)
