Creating Triangle Filters for Smoothing using Python
The 'binning' process consists in summing the energies (squared magnitude) within groups of adjacent FFT values. This will give you the total energy in a set of disjoint frequency bands.

magnitude spectrum
I have an ECQ signal of 360 Hz sampling frequency. I used an FFT to extract the frequency spectrum of my signal. Now I don't know exactly how to interpret this plot. How can I know the noise from ...

How should I remove obvious anomalies from spectral data?
I'm working with raman spectra and it seems that our spectrometer produces some anomalies at very specific wave numbers and I'm looking to remove them from the dataset. Here's a picture of 27 spectra ...

Frequency analysis to determine low-pass cut off frequency
I collected some data for a practical application, where the signal represents force data obtained from an impact of a punch against a force plate attached to a quasi-rigid rig (it moves once the ...

How to perform a Rubberband-Correction on spectroscopic data?
I basicaly understood how the Rubberband/Baseline-correction works.
The given spectrum is divided into (N) ranges.
The lowest points in every range are determined.
The initial baseline is built out ...
