It means that if 50/60Hz is not there somehow, you will end up seeing polarity-reversed 50/60Hz there. Play around with CleanLine parameters to see how it changes the results.</div><div><br></div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Jan 25, 2015 at 11:41 AM, Nastassja Fischer <span dir="ltr"><<a href="mailto:nlf.ufrj@gmail.com" target="_blank">nlf.ufrj@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi all,<div><br></div><div>I am experiencing a strange problem using Cleanline: when I use it to clear line noise, it "adds" some stereotyped artifacts which are not present if I just apply the low-pass filter at 45 Hz.
