With his project, a 3-axis Open Source FFT Spectrum Analyzer he is not only ... which is able to pick up vibrations within a frequency range of 0 to 1600 Hz on the X and Y axis.

This chapter describes the basic building blocks of FFT and IFFT in radix 2 exclusively. The decimation-in-time and decimation-in-frequency algorithms will be explained in detail. All other algorithms ...

As the name implies, the FFT is fast, and the result is the frequency components of the sampled data. [agp.cooper]’s “wrong” way to do it takes the Goertzel algorithm, which is used for ...
