Hi I found some issues with the code to calculate movement:
1) The notch filter was applied multiple times instead of changing the "order" of the filter. Running the filter multiple times seem to a…

when i use butterworth bandstop it adds noise. without them it shows less noise. i am using it on ecgdata.

At present we design filters as:
``` julia
digitalfilter(Lowpass(freq), Butterworth(order))
digitalfilter(Bandpass(freq1, freq2), Butterworth(order))
```
or equivalent, i.e., we specify filters in t…

Context:
1. For bandpass and bandstop filters, the qucsfilter interface is taking as input low and high corner frequencies
2. The qf_cauer filter is, on its end, taking as input an alternative repre…

Dear all,
I tried to applied a 50 Hz Notch filter on my data using letswave UI.
However, the parameters to fill seems wrong: it ask for low and high cut off frequencies. The Notch filter should on…
