Custom FIR Filter Phase Question

Question asked by jcaste on Sep 22, 2005
I am trying to build a custom FIR filter to match the magnitude and phase response of an existing analog filter. When I import the filter template and build the FIR filter, the bode plot looks fine in magnitude and phase. When I connect an impulse reponse input token and an analysis output token, the simulation results shows a phase reponse very different than the bode plot.
I'm at a loss on why it is different. Any help would be appreciated.
I have attached the svu file and filter template for reference.
