Bit By Bit Signal Processing, LLC

A business designing and supporting IP for signal processing applications.

BxBFFT Version 4.0

The BxBFFT is an amazing high-speed streaming FFT.  Some of its advantages:

The BxBFFT is well-suited for digital signal processing applications where the sample rate is many times the FPGA clock rate, such as cellular backhaul, radar systems, spectral switches, high-bandwidth beamformers, radio telescopes, test and measurement systems, analog system simulators, high-speed radios, and communication satellites.  For more information, see its product page:  BxBFFT. 


This Spectrum Analyzer, Oscilloscope, and Network Analyzer application demonstrates the BxBFFT.  It shows the BxBFFT operating flawlessly at real time rates on 5GHz bandwidths, with processing noise lower than the ADC noise floor.   It's also a useful application in its own right.  For more details, see its product page:  BxBApp.

Channelizer Tutorial

Bit by Bit Signal Processing is happy to provide a tutorial on derivation of the Polyphase Filter Bank (PFB) Channelizer.  This may help advanced customers understand how to use and analyze Bit by Bit's upcoming channelizer product.  Alternately, channelizer consulting is available.  The tutorial is available on the Tutorials page.
