Bode Plot

Problem
Freq5P1
This problems is designed to help you to understand Bode' plots better
by examining some simple plots. You may have a mathematical analysis
program available (e. g. Mathcad, Matlab, Mathematica, Maple, etc.).
You may use an analysis program if you wish.
Problem
5.1
Here the task is to generate a Bode' plot for the given transfer functions.
In every case, do the following:
-
Sketch the Bode' plot
before you use a program to generate the plots. Make sure that your
sketches include the following:
-
The phase plot, including
the asymptotes,
-
Corner frequencies,
-
Resonant peaks,
-
Estimates of slopes for
any long/straight segments,
-
DC gain values.
When you sketch the Bode' plot for G3(s), be sure you understand
whether this is actually G1(s) or G2(s).
