The Decibel ScaleFrequency 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
Bode Plots
Seven types of different factors that can appear in various combinations in a transfer function.
1. Gain K
2.
<< w1/T
>> 1/w T
3.
3.
<< wwo
>> wwo
w high

Active Filters
Active filters consist of combinations of resistors, capacitors, andop amps.
