I want to repeatly playback a set of data in time-domain. But there is a discontinuity between its beginning value and its end value, which creates a spike in data frequemcy spectrum. How do I apply a smooth filter in Matlab? Thanks

Dan

Hi Daniel,

You can use the filtfilt function to perform filtering of the data. For more information, you may refer to a similar question answered in the community,

Hope this helps!
