This works as expected:
```
responsetype = Lowpass(0.2)
designmethod = Elliptic(4, 0.5, 30)
coeffs = digitalfilter(responsetype, designmethod)
H,w = freqresp(coeffs)
```
but if I changed th…

Hi,
It seems that neither lowpass nor highpass functions are working.
One issue that i can see is that they return a float64 slice filled with 0s, due to this line:
output := make([]float64…

### Describe the feature and motivation
Torchvision and the python PIL library implement resizing operations that use a lowpass/anti-alias filter (see https://pytorch.org/vision/stable/generated/torc…

The lowpass filter in raw.info is not set correctly when uploading raw gdf file and doesn't update after filtering. I noticed it while trying to plot continuous data and getting a ZeroDivision error.

Hi. I encountered some problems with tracker modules playback.
The first one is lowpass filter sounding different if the sample rate is under 50kHz or above 50kHz. You can try playing the goddess.m…

With max frequency set to 20kh for DC filtering.
Algorithm idea (2-pole):
```c++

float lowpass = 0.f;
float highpass = 0.f;
float bandpass = 0.f;
void filter(const float freq, res, samplera…

A very nice side-effect of carrying around a time range is that it can greatly simplify the calculation of normalized cutoff frequencies. This allows the user to specify things in Hz, deferring coeff…

The RGB-to-YCbCr conversion code in libheif/heif_colorconversion.cc performs chroma subsampling by discarding samples only, without first lowpass filtering (taking a weighted average of) the samples. …

The thing is, Filtering is used quite a lot in Fluid, but, damn life, biquadFilter is pretty heavy operation in javascript (twices the CPU load).
I think it will be logical to have such folder struct…
