Description
Experience Level: Expert
General information for the app: The app does HRV analysis
Kind of development: Customization of existing app
Description of every page/module: Signal Processing on ECG signal for HRV analysis . I have an app that communicates with a BLE device and gets some ECG data.
The process is like that : ECG Signal -> Find RR peak -> Find RR interval -> apply cubic spline interpolation algo -> apply FFT -> get HRV analysis graph
I am stuck at applying the FFT , fast Fourier algorithm on data. But it doesn't provide the right results.
Description of requirements/features: Signal Processing on ECG signal for HRV analysis . I have an app that communicates with a BLE device and gets some ECG data.
The process is like that : ECG Signal -> Find RR peak -> Find RR interval -> apply cubic spline interpolation algo -> apply FFT -> get HRV analysis graph
I am stuck at applying the FFT , fast Fourier algorithm on data. But it doesn't provide the right results.
Specific technologies required: android, signal processing
Extra notes:

Can you outline what issue you are having with FFT?
Rahul S.08 Mar 2017Like I said, not producing the right results. Ex at 60 bpm straight i shud expect a peak at 1 Hz, for 120 at 2. But doesnt do like that
Edima U.09 Mar 2017Could you provide your FFT algorithm?
