Hi,

Not quite sure how to build/simulate this circuit in LTspice? Any ideas please!

Thanks again Bordodynov for your help.
Kindly, where can I find "K" block and "ddt" block in the LTspice?

Thanks

 

You can not use them, but use a controlled voltage source (similar to how I used to calculate the "COS")

Later today, I will try to play with it and see if i can understand the magic behind and let you know .... as much as i say am good about LTspice as much as i realize that i know nothing about it hahahaha

 

I am sorry.

 

I am sorry.

Oh now I see why I was getting a few simulation errors and wasn't getting a plot like the one you got ... I will have half day work today and planning to spend some time playing with the circuit... Thank you Bordodynov

 

I am sorry.

Wow now I started to understand how you built it.... so, these blocks that I was confused about are behavior voltages sources and that I have to use the assigned values for these behavioral sources including the Vin as well as setting the parameters ... Awesome maaaaaan ... what you did is gorgeous and very helpful .......... now I can easily start analyzing the waves, frequencies and other signals.
I wonder if I really learn this software very well, do I need to have a Oscilloscope machine anymore!?!?!

 

Circuitmaker (if you can get your hands on it), MATLAB have these
calculus blocks in it.
