a digital poles and zeros filter always offers 3 or 6 db/oct, depending on the use case, and you switch to a higher order by switches and gates which lets you choose to put filters in series or not.
this is more or less identical in both worlds.
if you actually want to use a "multiple switch" (i.e. many switches) to do that on a hardware surface is another question (you rather want to have a switch with 4 stages) but the internal logic in the circuit is always the same.
you *can *use a digital enviroment to design circuits which look *similar *to electric components, but of course one prerequisite would be that you *know *these analog components already. (and then it is questionable why you would need a computer program to simulate it?)
i am not really a pd user and i dont know which distribution has what gate and switch objects - but we can easily replace it using multiplications with 0 and 1.
this way it is even simpler to understand what happens.
