WebNov 22, 2013 · Once you have designed your filter you can apply it using the function filter or filtfilt. As an example, a simple way to go about this would be: [b,a] = butter (n, Wc) % low pass Butterworth filter with cutoff pi*Wc radians - choose the order of the filter n and cut-off frequency Wc to suit filtered_data = filter (b,a,original_data); Share
