However, it's been awhile since I've read some of the nitty gritty signal processing, and I forget what exactly this means or what the significance of it is.</div><div><br></div><div>Even though I was able to more or less replicate their current pipeline, I'd still like to understand what exactly setting the filter order is doing and what the significance of it may be. If anyone can explain this to me or set me in the right direction (a suggested chapter in Steve Luck or Matt Cohen's book, or a good article, for instance), I would greatly appreciate it. </div><div><br></div><div>Thanks,</div><div><br></div><div>Max<br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div style="font-size:small"><div>Max Cantor<br></div>Graduate Student</div><div style="font-size:small">Cognitive Neuroscience of Language Lab</div><span style="font-size:small">University of Colorado Boulder</span><br></div></div>
