Hi all,
I am trying to simulate my twin t bandpass filter with adjustable Q and constant gain but i am facing problem on it!!
i am using PSPICE schematic version 9.1.
i have included a potentialmeter on my circuit(as attached) on it. when i simulating it, error occur at the potentialmeter node, it showed " Less than 2 connections at node $N_0011".
below is the output file result:
Can anyone give me some advice on my problem?? appreciate it alot...
thanks thanks..
