B. Click "GO."  When the simulation is done, the Bode Plot appears showing the frequency response for this circuit. The gain (in red) and the phase (in blue) are displayed together.  You can also click on the "Show Results" button to show the Bode Plot at any time.

• The Bode Plot shows the phase and gain on the same graph plotted vs frequency. 
• The phase should be at least 25 degrees above -180, and preferably 45 degrees above -180. 
• The phase margin is the phase when the gain = 0 (crossover frequency). 
• We are not worried about the phase when the gain goes below zero. 
• If the phase gets close to -180 and comes back up, that is conditional stability which is still acceptable as long as the phase is good at the crossover frequency.
