Abstract

This article deals with a proposal of low-pass filter based on the microcontroller ATmega328 of the Arduino Uno platform. In the introduction we deal with theory of analog low-pass filter design, discrete low-pass filters, their advantages, and disadvantages. Digital filter design principle is shortly explained on a digital low-pass filter. The method of analog prototype filters was used. The transformation of an analog low-pass filter into the discrete low-pass equivalent filter was realized in two ways, in MATLAB environment and according to transformation coefficient. For the analog to a digital transformation of low-pass filter was necessary to estimate sampling frequency of Arduino. Digital low-pass filter was proposed by two ways and properties of analog low-pass filter and digital filters were compared.
