He is most noted for his work on the analysis and synthesis of electrical filters and his work marked the beginning of the field of network synthesis. Prior to his work, electronic filter design used techniques which accurately predicted filter behaviour only under unrealistic conditions."@en . "Cauer, Wilhelm"@en . . "1900-06-24Z"^^ . .
