WebSep 30, 2024 · Why does Firfilt-plugin run faster than the legacy EEGLAB filter? A. The Firfilt plugin does not use filtfilt to achieve zero-phase but shifts the signal by the filter’s group delay (NB: requiring ODD filter length/even filter order). So, the data are only filtered once with multi-threading (filtfilt does not seem to be multi-threading capable). Q. WebOct 18, 2024 · My code works, but is rather slow.
