Class, You may have used PSpice to do Bode plots in 211. If not, here are a couple of hints to make your outputs look like your hand drawings of Bode plots. Bode plots of magnitude or phase have logarithm of frequency on the horizontal axis. Bod magnitude plots have decibels on the vertical axis. Bode phase plots have degrees on the vertical axis. You can get the right answers for question 3 with linear axes but the shapes won't look familiar to you. First, to get the horizontal axis logarithmic, the easiest way is in the simulation settings. Edit your simulation profile to do an "AC Sweep/Noise" Analysis type and to choose "Logarithmic" or the "AC sweep type". Pick Start and End Frequency to bracket your expected pole frequency by a couple orders of magnitude. Usually 10 points/decade is fine. (Inserted optional note: One handy trick to mention here is that you can save key clicks by editing the simulation profile
