My understanding of filtering is very basic, but I believe in addition to the order of the filter this is largely determined by both the frequency band of interest and the transition bandwiths. Is this correct, and if so how can I retrieve these bandwiths as I did not specify them myself. If not, are there any other parameters that I should report in the methods section in addition to the filter order.</div><div class=""><br class=""></div><div class="">Thanks in advance,</div><div class=""><br class=""></div><div class="">Dirk</div><div class=""><span style="color: rgb(212, 212, 212); font-family: Menlo, Monaco, "Courier New", monospace; white-space: pre; background-color: rgb(30, 30, 30);" class=""><br class=""></span></div><div class=""><br class=""></div></body></html>
