                   Hello guys,

          I am using an NRF chip with Cortex M4. Currently I am reading data from an accelerometer (12 signed bit ADC) and I have to get peak velocity. For that I am using the Omega arithmetic algorithm, as follows:

             - remove offset from…

    I have been trying to use the RFFT functions in the CMSIS DSP library which has been giving me some confusing outputs.

    From the documentation:

    Looking at the data, we see that we can uniquely represent the FFT using only N/2 complex numbers. These are…
