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. WebMay 16, 2024 · It also explains how 'Filter Design Toolbox' can be made use of in MATLAB to design desired filters on the go.

WebJan 24, 2016 · It is beneficial to work with the zeros of a discrete filter; the zeros of an FIR filter define it to within a gain factor. For a phase linear FIR filter, the impulse response will be symmetric. The zeros come in several categories (the following assumes a sampling rate of 1): 1. Zeros at z=0. These just introduce delay. 2. Zeros at +/- 1. WebOct 17, 2024 · Hi, I have to filter large amount of data with a FIR filter. My code works, but is rather slow.
