Original sentence: , Wave Filter, US patent 2 002 216, p2 lines31-34, filed 7 June 1933, issued 21 May 1935.Bode, Hendrik W.It describes filter sections that are practical for very low values of m in a bridged T topology.The material is more suited to m-derived filter, or composite image filter.Uses Bartlett in the paper
Edited sentence: Any symmetrical network can be transformed into any other symmetrical network by the same method, that is, by first transforming into the intermediate lattice form (omitted for clarity from the above example transform) and from the lattice form into the required target form.As with the example, this will generally result in negative elements except in special cases.Composite image filter (Bode circuit).DescriptionNetworkTransformed network.It can sometimes be useful to make such a transformation, not for the purposes of actually building the transformed circuit, but rather, for the purposes of aiding understanding of how the original circuit is working.Network analysis (electrical circuits).The action of this circuit is clear if it is transformed into T topology - in this form there is a negative resistance in the shunt branch which can be made to be exactly equal to the positive parasitic resistance of the inductor.The circuit is due to Hendrik Bode who claims that the addition of the bridging resistor of a suitable value will cancel the parasitic resistance of the shunt inductor.The following circuit in bridged-T topology is a modification of a mid-series m-derived filter T-section.Transform 3.5Transform of a bridged-T low-pass filter section to a T-section
