A Microcontroller Based FIR Filter With Dynamic Stabilization of Sampling Frequency

Abstract

A real time FIR filter has been implemented using an ATmega2560 based microcontroller. The digital filter designed theoretically cannot be implemented in practice until the sampling frequency remains constant on different boards, using different versions of compilers and the order of the filter, therefore, can be assessed accurately. Present work is a solution of such inter-linked problems.
