Arno (and ohters), I gave a llok at the PZ analysis, the code is very confusing (I did not understood how it is supposed to work). To test it against some "trusted" code. In Vladimirescu's SPICEbook there is a t-bridge filter: BRIDGE-T FILTER V1 1 0 12 AC 1 C1 1 2 1U C2 2 3 1U R3 2 0 1K R4 1 3 1K * .OP .PZ 1 0 3 0 VOL PZ .PRINT PZ ALL * .END The simulation aborted without giving any result. This filter has two poles and two zeroes. Paolo
