After long time i am able to find Laplace transform function but cant understand the bode plot which give information of frequency response and magnitude i think

plaese anyway here how can push my thinking ahead in it?

You can't get a whole semester course from an online forum. I suggest that you try hard to understand the wiki article linked. After that, you can return here with more specific questions and we will try to help.

how to draw bode plot?

i was not able to understand at that time.You can't get a whole semester course

Should both diagrams be correlated?

no because one show for phase and another show for magnitude.

Sorry - but this is not an answer to my question (I did not ask if both are "equal").no because one show for phase and another show for magnitude.

The complete BODE diagram for each frequency dependent network consists of TWO drawings: (a) Magnitude vs. frequency and (b) phase vs. frequency.

You have shown two such diagrams - however, it seems that they are not for the same circuit (because the must be correlated!).

i have no idea get it from wiki.

any way how they should be correlated..

That is pure mathematics:

So you have two functions which are, of course, correlated because they come from the same circuit.

how to learn bode plot??

Simple answer: Learn how to produce a graphical representation of magnitude and phase of a simple frequency-dependent network (R-C combination).how to learn bode plot??

Start with H(jw)=Vout/Vin and calculate magnitude and phase functions. This requires some basic math knowledge.

i have got Vo/Vi=s+1/s+2Start with H(jw)=Vout/Vin and calculate magnitude and phase functions. This requires some basic math knowledge.

I suppose you mean (s+1)/(s+2), correct?i have got Vo/Vi=s+1/s+2

* Do you know the meaning of "s"?

* Are you able to write down the expressions for magnitude and phase?
