When I ran the FFT with the attached data samples, the result was significantly different from the Python FFT result. I tested it on a Cortex-M3 using the arm_rfft_f32 function and obtained the ...

I am computing the real FFT with arm_rfft_q15. To make sure my code is correct, I am sending back and forth my data to a python script that runs the cmsis-dsp package available on PyPI. The issue I am ...

This post is intended for developers who do not have expert knowledge of FFT. The sampling frequency of AVISS's MEMS accelerometer model AV308 is 1600 Hz. For more expert knowledge on sampling ...

Working with Fast Fourier Transforms (FFT) in Python? While SciPy and NumPy have their own FFT modules, pyFFTW is a powerful alternative that offers a significant PERFORMANCE BOOST... but only if you ...
