Solution:
fc=4kHzK=500Ω
L=Kπfc=500π×4×103=39.79mHC=1πfcK=1π×4×103×500=0.16μf
The ,
T
the section consists of an inductor
L/2
i.e
19.9mH
in each series branch and a capacitor of 0.16μf in the shunt branch
The π section consist of an inductor of 39.79 mH in series branch and a capacitor of c/2 i.é 0.08μf in each shunt branch.
