Last night I implemented an active 4 pole filter designed with Filterlab.
It did not work as expected (my expectations could be wrong, I know ).
I would like to simulate it. How to actually do the frequency sweeping in LTSpice?
Whatever I try I get nothing or a message asking for "AC 1" to be present.
Can anyone mention step by step how could I get there?
PD: not that I want make simple things, difficult, but what if I have more than one AC signal source present?
Gracias for any help.
