In filter technology, the synthesis techniques of Cauer and Darlington, among others, have come into wide-spread use. With the swing to higher and higher frequencies, these techniques have enabled circuit designers to obtain high performance with coils of moderate Q in L-C circuits, with quartz resonators of high Q, and with mechanical and ceramic resonators with desirable qualities somewhere between those of L-C components and of quartz.

Mathematics as an enabling technology in the history of communications and control engineering

Systems ideas that originated with communications engineering were extended to other domains such as control engineering, and a highly significant synergetic rela tionship developed between the mathematical modelling of Systems and components, the design of instrumentation, the development of the analogue computer, and the designs of devices and Systems.
