Assume that you're knowing the PCB stack and the geometry of the conductor.You're computing the capacitance per mm and inductance per mm and also the total resistance of the conductor.
That means you can shape the transfer function from the eletrical RLC circuit:
To this transfer function.
So that means you got the transfer function of the conductor. Then you need the transfer function from the driver and the load.
Assume that the driver and the load is a logic IC. How can I find the resistance, capacitace and the inductace from them?
