I generated a sinus signal from 0kHz to 2MHz and my signal passes the following spectrums: For band1 in my analysis filterbank: 600kHz to 1000kHz 1000kHz to 1300kHz
for band2 in my analysis filterbank: 300kHz to 600kHz 600kHz to 1000kHz 1000kHz to 1300kHz 1300kHz to 1600kHz for band3 in my analysis filterbank: 300kHz to 600kHz 600kHz to 1000kHz 1300kHz to 1600kHz so i think the band_pass i not useful for the analysis filterbank at all ?! Any idea how to set up the analysis filterbank, so that i get for band1: 1MHz to 1.33MHz band2: 1.33MHz to 1.66MHz band3: 1.66MHz to 2MHz ???
