Bartlett's bisection theorem

From Wikipedia, the free encyclopedia

Bartlett's Bisection Theorem is a theorem in electronics. It states that a filter network operating between equal input and output resistance terminations may be modified for unequal source and load resistors if the filter circuit is symmetrical. If a symmetrical network is bisected and one half is impedance-scaled, the response shape will remain the same.
