WebAs we can see in the output, using a high pass butterworth filter we are able to filter the signal of 3000 random samples. Conclusion Butterworth filters are used to get maximally flat output within the defined passband. In Matlab, we use ‘butter’ command to design a Butterworth filter. WebIntroduction to Filter Function in Matlab This function filters the data sequence by using a digital filter, the output of filtering is basically smoothening or sharpening of signal (eliminating specific frequency range). It is direct from II implementation of signal (standard difference equation).
