<div dir="ltr">Dear Marwa,<div><br></div><div>Sampling rate of 250Hz means your EEG recorder recorded 250 points per second. Therefore, if your data is 250Hz sampled, you can assume that each point (technically, interval length between the points) is 4 ms long.</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, May 15, 2015 at 1:58 PM, Roma Nojan <span dir="ltr"><<a href="mailto:roma.nojan@yahoo.com" target="_blank">roma.nojan@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:bookman old style,new york,times,serif;font-size:16px"><div>Dear all:</div><div dir="ltr">I am a Master student.
