The period of sample clock in the model is 1e-3 but the sampling period block parameter of this block is not 1e-3. I also note that the size of input buffer is 2048 but the simulation stops at 2, i.e., 2000 points. I assume no FFT is computed until at least 2048 points are placed in the buffer.<br>Ramine<br></div><div><br></div><hr><blockquote style="border-left:2px solid #1010ff;margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt"><b>De: </b>"Nikolay Strelkov" <<a href="mailto:n.strelkov@gmail.com" target="_blank">n.strelkov@gmail.com</a>><br><b>À: </b><a href="mailto:scicos@inria.fr" target="_blank">scicos@inria.fr</a>, <a href="mailto:users@lists.scilab.org" target="_blank">users@lists.scilab.org</a>, "alan layec" <<a href="mailto:alan.layec@cermics.enpc.fr" target="_blank">alan.layec@cermics.enpc.fr</a>><br><b>Envoyé: </b>Jeudi 25 Décembre 2014 19:58:20<br><b>Objet: </b>[scicos] Fwd: Question about PSPECSCOPE_с in Modnum toolbox<div><div><br><div><br></div><div dir="ltr"><div><div>Dear ScicosLab and Scilab community!<br><div><br></div></div>I have a question about Modnum toolbox, but can't get response from its developer.<br></div>Can anybody help me?<br><div><br></div>With best regards,<br>maintainer of <a href="http://atoms.scilab.org/toolboxes/Mathieu" target="_blank">Mathieu functions toolbox for Scilab</a>,<br>IEEE member, Ph.D.,<br>Nikolay Strelkov.<br><div><br><div><br></div><div><div><div><div class="gmail_quote">---------- Forwarded message ----------<br>From: <b class="gmail_sendername">Nikolay Strelkov</b> <span dir="ltr"><<a href="mailto:n.strelkov@ieee.org" target="_blank">n.strelkov@ieee.org</a>></span><br>Date: 2014-12-13 1:13 GMT+03:00<br>Subject: Question about PSPECSCOPE_с in Modnum toolbox<br>To: <a href="mailto:alan.layec@cermics.enpc.fr" target="_blank">alan.layec@cermics.enpc.fr</a><br><div><br></div><br><p dir="ltr">Dear Alan!</p>
<p dir="ltr">Thank you for your great Modnum toolbox. I use it from 2009 year for modelling of some control system elements.</p>
<p dir="ltr">Today I use Modnum 4.3b with ScicosLab 4.4.1.<br>
I want to create a simple demo with PSPECSCOPE_с block for calculating and plotting FFT spectrum of a simple sine wave.</p>
<p dir="ltr">As a starting point I created small file in Scilab 5.5.1 which plots and calculates FFT spectrum. It is in attachment, and it works as I expect.</p>
<p dir="ltr">I created Scicos model file, but I can't understand how to set correct options for PSPECSCOPE_с block for getting expected FFT. The model file is in attachment.</p>
<p dir="ltr">Could you please help me to set up PSPECSCOPE_с block?</p>
<p dir="ltr">With best regards,<br>
