    Hi everyone,
    Basicly, I am trying to simulate a dc decoupling filter (a capacitor in series with a resistor) using PSpice. However, I found that it takes long time for the mean value of the output signal to reach 0V. I realized that if I use a smaller resistor, the converge time will be reduced, but the output signal will be distorted.
    So are there any other way to reduce the converge time in simulation, such like setting an initial voltage or current?:confused:
    By the way, how to set initial voltage and current in PSpice:)?

    The Pspice simulation file is in the attachment.

    Thanks a lot.
