[mathcad] Angles larger than 180
Author: Esteban Sanchis    Posted: Wed, 29 Jul 2009 19:21:26 +0200
Hi everyone I am trying to plot a Bode diagram, but want to see angles larger than 180º (pi/2). Funtions ARG or ATAN2 "jump" when they arraive at 180º. Placing some minus signs helps but only for the first jump and not for the follwoing. Any suggestion? Thank you everybody.

This problem can only be totally avoided if you add the individual phases from each factor in the Bode expression. If you use the Bode plots in connection with control systems then you might find the enclosed program useful. -----Original Message----- From: Esteban Sanchis Sent: 29. juli 2009 19:21 To: /> Subject: [mathcad] Angles larger than 180 Hi everyone I am trying to plot a Bode diagram, but want to see angles larger than 180º (pi/2).

use the 'angle' function. It specifically uses 0-360 deg. -----Original Message----- From: Esteban Sanchis /> Sent: 29 July 2009 6:21 PM To: /> Subject: [mathcad] Angles larger than 180 Hi everyone I am trying to plot a Bode diagram, but want to see angles larger than 180º (pi/2).
