Re: [Discuss-gnuradio] overlapping channels in polyphase channelizer

[Marcus Müller]

Hi Ben,

yes, that should work; as you've guessed, the polyphase channelizer doesn't really "care" what your filter looks like. That includes the band edges, too, so your last channel will overlap with your first.

Best regards,
Marcus

Is it possible to have overlapping channels in a polyphase channelizer? say you have 10MHz of bandwidth, and you want to break it up into 10 channels, each 2MHz wide with the center frequencies being 1MHz apart. 

would you just set the taps to have the right bw and lowpass filter width (in this case it would be 1MHz to create a 2MHz channel), then set the number of outputs on the channelizer block in grc to be 10?

thanks,
