My data doesn't contain NaNs, inf or similar.<br /><br />It works fine until I reduce the upper cut-off frequency e.g. to 10 Hz. Then I only get NaNs.<br /><br />After experimenting a little bit I found that reducing the filter order (originally 10) solves the problem. I found this in the help of butter:<br /><br />Limitations<br /><br /><i><br />In general, you should use the [z,p,k] syntaxto design IIR filters. To analyze or implement your filter, you canthen use the [z,p,k] output with zp2sos and an sos dfilt structure. For higher order filters(possibly starting as low as order 8), numerical problems due to roundofferrors may occur when forming the transfer function using the [b,a] syntax<br /></i><br /><br />When I use filter orders <= 8 I can choose any cut-off frequencies without a problem.<br /><br />Hope this helps someone with the same problems.<br /><br />Manuelnoreply@blogger.comtag:blogger.com,1999:blog-4133180739150180147.post-62253044871813407302014-01-03T21:13:02.603-08:002014-01-03T21:13:02.603-08:00Thank you!
