Distributed-element filters are not localised in discrete capacitors, inductors, and resistors as they are in conventional filters. Warren P. Sykes founded the major field of distributed-Element circuits in the years before World War II and published a paper on the subject in 1937.

About Distributed-element filter in brief
Distributed-element filters are not localised in discrete capacitors, inductors, and resistors as they are in conventional filters. Conventional filters are constructed from inductors and capacitors. In the distributed view of circuits, the elements are distributed along the length of conductors and are inextricably mixed together. There is no precise frequency above which distributed element filters must be used but they are especially associated with the microwave band. The technology can be found in several mass-produced consumer items, such as the converters used with satellite television dishes. For clarity of presentation, the diagrams in this article are drawn with the components implemented in stripline format. Planar transmission line formats are popular because they can be implemented using established printed circuit board manufacturing techniques. The structures shown can also be adapted using microstrip or buriedpline techniques, although some are more suitable than others. The open wire implementations of a number of these structures are shown in the second column of column 3 and open wire equivalents of wire are shown for most other wire types. The most noticeable difference in behaviour between a distributed-element filter and its lumped-element approximation is that the former will have multiple passband replicas of the lumping-element prototype passband, because transmission-line transfer characteristics repeat at harmonic intervals. These spurious passbands are undesirable in most cases.
A major paper on the subject was published by Sykes and Mason in 1937, and may contain the first electrical design that moves away from a lumped element analysis. Warren P. Sykes founded the major field of distributed-Element circuits in the years before World War II and published a paper on the subject in 1937. The paper was published on subject on the subject of electrical design and was published in 1937 by Syke and Mason and may also contain the work on electrical analysis which may contain a patent for a distributed element design. The work was published much earlier than that on electrical design, which was first published in 1927, and contains the work of Sykes, Mason and Sykes’ co-authors. The papers were published on the subject of electrical design and may contain the work of Sykes and Mason’s co-authors on electrical design and electronic networking. The first paper was published in 1927, and the work was first published in 1928, and the first patent was for a design for a distributed element filter. The second paper was published in 1929, and the work was later published by Sykes and Sykes’ co-workers on the subject of electrical networks in the years before World War II and in the years after World War II. The first patent for a distributed element filter was published in 1929, and it was received by P. Mason in 1931, and he was the first to publish a paper on the subject in the years after World War II, which was also published by P. Mason and Syke.
