If you’ve ever wanted to make your own VU meter but were scared off by the signal process you need to study this tutorial. The one drawback to the hardware choices made here is that there are ...

Centar Fixed-point FFT The approach Centar uses for its fixed-point circuits is a very sophisticated block-like floating-point approach. Centar’s programmable circuits start with a user chosen matrix ...

With his project, a 3-axis Open Source FFT Spectrum Analyzer he is not only entering the Hackaday Prize 2016 but also the highly contested field of acoustic defect recognition. For the hardware ...

The transform computation is based on a new matrix formulation of the discreet Fourier transform1 (DFT) which decomposes it into structured sets of b-point DFTs. This avoids the inherent ...
