WebDesigning the filter. Let's start with the basics of designing the Butterworth-filter in Matlab. Here, we can only define a filter using normalized frequencies. Therefore we need to know the sampling frequency fs to determine the normalized frequency fn like this: fn = f/fs. Then we need the order order and the two cutoff-frequencies fc1 and fc2.
