Currently the velocities are estimated using a Savitsky-Golay filter, which tries to fit (in the least-squares sense) a 2nd-order polynomial to the last N joint position measurements, and then uses th…

Hi thanks for the library. Testing the Butterworth worked great with i2s audio and the ESP32.
I would like to test coefficients with the FIRFilter, but having trouble initiating the filter and there …

from https://github.com/scipy/scipy/pull/3717, `signal.dimpulse` produces the wrong results for higher-order filters, compared to `sosfilt`. 7th order butterworth is fine:

Hi, KFR Community,
Thanks for the help in advance for two issues.
1) how to get the transfer function coefficients of IIR, such as "the 8th-order Chebyshev type I filter, lowpass" below
```

I think this would be a fun addition to the current 1.2 Equalizer.

Hi there,
I see the implementation require high knowledge of C++ coding. I have been through the example of the Butterworth filter, and I am keen on getting the b and a coefficients to compare with …

simple but effect and , 看了/跑了几个例子,感觉多多少少会在视频的运动幅度上有些许损失。amazing!

There is wrapper for FIR filters from DSP.jl.
What about IIR filters, like butter etc.?

Because (e.g.) the IMU lab uses `scipy.signal.butter`
