Dear All,
Hope all is well.
I am trying to understand the bode plot in semi log graph of below transfer function.
The simplify transfer function form:
Constant factor:
db
1 pole at the origin :
1 zero at z1 = 20
2 poles: at p1 = 0.5 and p2=40
Now its very difficult for me understand bode Gain and Phase plot :
Could anybody make me understand how to draw above plot of Gain and Phase and how to calculate Gain and Phase Margin.
Please go step by step so it would be easy to understand.
Lets say
Why bold black line statred from 60db ???
Where is pole and zero added and what is what changes in db/decade.???
How do we calculate db/decade changes ???
Please consider me as a novice.
Thanks !!!
