Bit by Bit Signal Processing
Bit by Bit Signal Processing
A business designing and supporting IP for signal processing applications, including one of the world's best high-speed Fast Fourier Transforms (FFTs) and best high-speed digital channelizers.
The BxBFFT is an amazing world-leading high-speed streaming FFT IP core. It's now at version 6.0, and supports AMD/Xilinx and Altera FPGAs with a path to ASICs. It has multiple industrial, academic, and military customers. It has improved the speed, resources, and power of their designs. See the BxBFFT product page.
The BxBChan is an amazing high-speed Polyphase Filter Bank based on the BxBFFT. Now at version 3.0, it has military and academic customers. It supports AMD/Xilinx and Altera FPGAs with a path to ASICs. It has improved the speed, resources and power of customer designs, even beyond what was achievable with the BxBFFT alone. See the BxBChan product page.
This Spectrum Analyzer, Oscilloscope, and Network Analyzer application was an early demonstration of the BxBFFT in operation. It shows the BxBFFT operating flawlessly at real time rates on 5GHz bandwidths, with processing noise below the noise floor, at more than 100dBFS down. It's also a useful application in its own right. For more details, see the BxBApp product page.
Bit by Bit Signal Processing has provided a tutorial on derivation of the Polyphase Filter Bank (PFB) Channelizer. This may help advanced customers understand how to use Bit by Bit's new BxBChan channelizer product. Alternately, channelizer consulting is available. See the Tutorials page.
Bit by Bit Signal Processing was founded by Ross Martin in 2018, after a career designing hardware and algorithms for processing data for radar systems, optical imaging systems, and satellite communication systems. The business supplies Intellectual Property supporting high speed signal processing applications.
