Hi John, You can do a single FPGA Polyphase filter quite easily on a PicoSDR, using Xilinx System Generator FIR Compiler and control your FPGA design from GNU Radio: http://nutaq.com/en/blog/using-nutaqs-mbdk-gnu-radio-%E2%80%93-part-2-implementing-polyphase-channelizer Regards, ~Tristan De : address@hidden [mailto:address@hidden De la part de John Wilson

Objet : Re: [Discuss-gnuradio] How many multiple/simultaneous PLLs can I have running on USRP2? Sorry to dig up an old thread, but does anyone know of anyone who's implemented a polyphase filter bank on a USRP FPGA? John On Thu, May 9, 2013 at 12:02 AM, Marcus D.

It's all in the computer, unless you do an FPGA-based implementation. Gnu Radio blocks run on the host machine, not the USRP hardware.
I admit to being a little bit surprised that you don't know that already, given how long you've been posting things to this list,
and using USRP hardware.
