5. The Decibel Scale
Frequency Response drawn using Bode plots. The Bode plots are based on
logarithms, so it is important to keep the following properties of logarithms
:
Gain in the Bode Plots, use Decibel scale and usually remark as GdB

6. Bode Plots
Seven types of different factors that can appear in various
combinations in a transfer function.
