I want to find phase shift between A and B output (and also A-C & A-D)
I use EWB to find phase shift but I need Formula for phase shift and also gain of A-B (not in dB)(A-C & A-D) (Gain VB/VA VC/VA VD/VA)
Any one can help me to find formula of gain and shift phase?
I know KVL(mesh) and KCL(Nodal). but I can not find gain(loss) I don't know why? I think there is simple formula for this job!
Just tell how can I find Voltage of A and B I can do it for other nodes.
Get rid of the opamp, etc., and just keep the 3 CR sections. Apply a 1 volt source to the input (left end) and solve the network for the voltages at the other nodes. Then take the ratio of VB/VA and you have the gain for that pair of nodes. Solve the rest in a similar fashion.
Show your work if you still have a problem
Have a look at this for some ideas (the C's and R's are swapped, but you should be able to figure out how to deal with that):
