How to find a linear RLC circuit from its transfer function?
I have a transfer function, for example:
$$H(s)= P\frac{10}{s(s+5)(s+9)}$$
See the figure below.
How do I make a linear RLC circuit from this transfer function, without using an op-amp, but a linear ...

LTI system Bode curve
Given an RLC circuit, I needed to find the transfer function, which I did. Now I need to find R and L so that the next two conditions are met:
The overshoot is 25%
The first peak time is t = 3
The ...

What is meant by the shifting property of the companion form?
I am going through the book "Linear System Theory and Design" by Chi-Tsong Chen, where they talk about the controllable canonical form and how it is a realization of a transfer matrix.
In ...

Why are state variables sufficient to describe the exact future temporal dynamics of a system
I'm confused about state-space state variables. How come knowing the initial conditions with the input 'determine completely the future behavior of the system'? From such knowledge, I can only ...
