    I am trying to understand the filtering effect of a pi filter on various frequencies. The hard part is deriving the transfer function for that pi filter.
    The goal is to plot the bode plot and manipulate the cut-off frequencies to achieve those levels in the chart.
    This filter is going to be used at the input of a buck regulator that is operating at 250 khz.

    What would be the best way to approach the filter design?

    Your help is greatly appreciated.
