Finally, we can solve the equation for the ratio of output to input for our control system, resulting in the transfer function: Transform Method with Mesh Analysis ...

Transfer functions analyze how system output changes depending on the input. This article details how to implement a transfer function in LTspice, comparing ideal vs. modeled ...

Note that the arrow sign “→” in Eqs. 19 and 20, and in other equations to come, is the symbolic equal sign in Mathcad. We have the following observations with Eqs. 19 and 20.
