Transfer Function numerator denominator
The Decibel ScaleFrequency Response drawn using Bode plots. The Bode plots are based onlogarithms, so it is important to keep the following properties of logarithms :Gain in the Bode Plots, use Decibel scale and usually remark as GdB
Bode PlotsSeven types of different factors that can appear in various combinationsin a transfer function.
1. Gain K
