A library for creating digital lowpass filter. The image shows a 0.1 Hz sine wave signal with an added 50 Hz and 150 Hz sine wave to simulate noise. The raw signal is shown in blue and the filtered ...

A 3d printable motorised filter wheel. The wheel is motorised with a 28BYJ-48 stepper with control provided by an Arduino Uno. The firmware is compatible with Xagyl Indi and ASCOM drivers. - chemis ...

In this article is proposed the flexible design and the automatic modification in the digital filter response, IIR or FIR by using Arduino DUE supported by Matlab libraries. The scheme proposed allows ...

Nowadays, due to the rapid development of digital platforms, digital signal processing has become realizable into small size processors. The purpose of this study is to test the filtering process on ...
