Where is the implicit equation for linear two-ports derived from?
I have been told that linear two port networks can be described by the following implicit equations. $$π_1π’_1+π_2π’_2+π_1π_1+π_2π_2=0\text{ and }π_3π’_1+a_4π’_2+π_3π_1+π_4i_2=0$$ My problem ...

RC filter for a fast delayed ramp
Consider simple RC networks with 3 external terminals (GND, IN, and OUT) and, at most, 4 total components. To be clear, each component is either a resistor or a capacitor. For a 1V voltage step on IN, ...
