graphical spectrum analyzer with FPGA - Jürgen Schuhmacher 2005

A graphic spectrum analyzer with 192 bands from 10 Hz to 20.000 Hz in logarithmic scale running on a Xilinx Virtex test system for noise measurement. It also works in the S3 environment. The analyzer uses e.g. the multi pipeline fiter used already in the vhdl-audio-filter.

 The first analyzer was done in the home made fpga platform, see:
