Homework Help: Short/Open Circuit time constant method: b1

  1. Oct 8, 2013 #1
    1. The problem statement, all variables and given/known data

    The short circuit time constant method for determining 3dB point for high pass filter says

    b1= the sum of short circuit time constant seen by each individual capcitor with the all other capacitor replaced by short circuit.

    b1 is also = the sum of pole1, pole2.....

    I am not very convince by this statement. How should I see that
    [the sum of poles] = b1 = [the sum of short circuit time constant seen by each capacitor] ?

    Thank you
